Owning a swimming pool has definite perks, offering an escape from the summer heat. But let’s be honest: pool maintenance requires time and effort. An automatic pool cover provides many advantages that can boost your overall pool experience, making summer days even more enjoyable by reducing some of your  pool maintenance duties. If you are on the fence about buying one, several benefits of automatic pool covers may influence your decision.

Another Layer of Pool Safety

Automatic pool covers help protect families. When adult supervision is not possible, an automatic pool cover can be closed in a matter of seconds. Many automatic covers support significant weight, protecting against accidental falls into the pool. While they are not the cheapest pool accessory, the added layer of protection is invaluable for pool owners with children and pets. Furthermore, some homeowner insurance companies offer discounts if you install one.

Reduced Maintenance Efforts

Keeping your pool clean can be a constant chore, especially if your pool is surrounded by trees and plants that deposit debris. Automatic pool covers make this much more manageable, providing a welcome relief from the daily cleaning routine. By keeping your pool covered when not in use, debris, including leaves, twigs, and dirt, is kept out of the water, drastically reducing the need for frequent cleaning. Using a pool cover saves you time and energy that would otherwise be spent manually cleaning the pool or running vacuum systems.

Additionally, automatic pool covers help minimize chemical degradation. Chlorine and other pool chemicals break down faster when exposed to sunlight. Covering the pool reduces UV exposure, allowing the chemicals to last longer and reducing the amount you need to add, leading to lower chemical costs over time.

Energy Savings

Heating a pool can be a significant expense. Automatic pool covers help retain heat in the pool, which reduces the amount of energy needed to maintain the water temperature.  Energy.Gov found that a cover can lower heating costs between 50% and 70%. Automatic pool covers also decrease water evaporation, conserving water and resources used to refill and reheat the pool water. A pool cover can help you reduce your overall carbon footprint while still having the luxury of a heated swim.

Convenience and Ease of Use

Manual pool covers can be inconvenient to use, sometimes requiring multiple people and considerable effort to operate. On the other hand, automatic pool covers eliminate that hassle. You can cover or uncover your pool by pushing a button or turning a key. When it’s easy to use, you will be more likely to cover the pool when it’s not in use.

Extended Pool Season

Another significant advantage of automatic pool covers is extending your swimming season. By keeping the water warmer, you can comfortably swim earlier in the spring and later into the fall. The added warmth turns your fiberglass pool into an inviting oasis despite cooler outdoor air temperatures and allows you and your family to enjoy it almost year-round. Whether hosting late summer barbecues or enjoying a quiet swim while the kids are in school, the longer swim season gives you more opportunities to use your pool.

Aesthetic Appeal and Increased Property Value

Automatic pool covers come in various styles, shapes, and colors to accommodate multiple  pool designs, allowing you to choose an option that complements your outdoor space. When closed, these covers can blend seamlessly with your deck, creating a polished and tidy look that enhances the overall aesthetic of your backyard. The added visual appeal can make your pool area more inviting for gatherings and relaxation.

Additionally, investing in an automatic pool cover can significantly increase the overall value of your property. Homebuyers often seek features that promote safety, convenience, and energy efficiency. A pool equipped with an automatic cover can set your home apart in a competitive market, making it a wise investment for the future.

Is an Automatic Pool Cover Right For You?

An automatic pool cover is not just a luxury; it’s a practical investment that brings numerous benefits. Check with your installer or pool dealer for details about the cover manufacturer, warranties, and maintenance required to enjoy your pool to the fullest, knowing you’ve made a smart choice for safety, savings, and style.

How Do I Backwash a Sand Filter in My Fiberglass Pool?

Posted on by kristin

Keeping your fiberglass pool sparkling clean doesn’t need to be complicated, but it does require some regular care. One of the most critical parts of routine pool maintenance is making sure your filter runs efficiently. If you have a sand filter, you’ll need to know how to backwash it properly to keep your water clear and your system in top shape. The good news? Backwashing is quick, easy, and an essential step toward making every swim as refreshing as the first of the season.

Every pool relies on a filter to remove dirt, debris, and tiny particles that swimmers don’t want sharing the water. There are three main types of filters, each with their own strengths.

  • Cartridge Filters: Low-maintenance and energy-efficient. Just rinse or replace the cartridges to keep the water clear.
  • Diatomaceous Earth (DE) Filters: Ultra-fine filtration for the clearest water possible, but they require a little extra care and handling.
  • Sand Filters: Durable, cost-effective, and easy to maintain. A quick backwash flushes out trapped debris, restoring flow and clarity with minimal hassle.

What is Pool Filter Backwashing?

Backwashing a sand filter is a maintenance procedure that cleans the filter and ensures it operates efficiently. Over time, as water pumps through the sand filter, the sand traps debris and particles to remove them from the pool water. The process gradually accumulates dirt and debris in the filter, which can decrease efficiency and encourage cloudy pool water.

Backwashing temporarily reverses the water flow through the sand filter. Instead of dirty water coming in and clean water going out, backwashing pumps clean water backward through the filter. The reverse flow lifts and flushes trapped debris from the sand bed and the filter through a waste line or drain.

During backwashing, the sand within the filter loosens and allows for trapped debris to make its way out of the system. After backwashing, return the filtration system to its normal operation of filtering the pool water again. Backwashing sand filters is essential for maintaining their ability to clean the pool water effectively and should be a regular part of your pool’s maintenance routine.

Why is Backwashing My Pool’s Sand Filter So Important?

Backwashing keeps your filter functioning properly and clear of debris. It also helps to keep your water clear. Even if you are meticulous about other maintenance and consistently add chlorine to the chlorinator, check its settings, brush all the pool surfaces, empty skimmer baskets, vacuum, test water chemistry, and maintain the correct water level, your pool water will still turn cloudy if you forget to clean the filter. 

What Happens If I Don’t Backwash My Pool’s Sand Filter?

If you don’t backwash your sand filter for some time, you may notice your water getting cloudy or more debris making its way to the surface of your pool water. Other maintenance tasks are still essential, but none will replace the need for backwashing the pool’s sand filter..

How Do I Know If I Need to Backwash My Pool’s Sand Filter?

You will need to check your filter system’s pressure gauge regularly. When clean, your filter will generate a typical reading that you should note as its standard baseline. You’ll know it’s time to backwash once the gauge reaches 8 to 10 psi above your baseline reading. Your water may also look cloudy or dirty when the filter needs backwashing.

What is the Proper Way to Backwash My Pool’s Sand Filter?

  1. Turn the filter system off. 
  2. Remove, empty, and replace the skimmer basket.
  3. Attach a backwash hose to your filter’s backwash port.
  4. Turn your multi-port valve to Backwash. Never turn the multi-port valve handle while the pool filter is on and running.
  5. Turn your filter system back on. Water should flow out the backwash port and through the hose.
  6. Let the water run for about two minutes or until the water runs clear in the site glass.
  7. Turn the filter system off again.
  8. Turn the multi-port valve to Rinse. 
  9. Turn the filter system back on and rinse the filter for about 30 to 60 seconds.
  10. Turn the system off.
  11. Turn the multi-port valve to Filter.
  12. Turn the system back on.

What Are Some Potential Issues With Backwashing a Pool’s Sand Filter?

Sand in the Pool

If you notice sand in your pool during or after backwashing, then you might have cracked off laterals or piping inside the filter. You may also have too much sand in the filter. The open space from the top of the filter to the sand line is called “freeboard,” and having enough space is essential for preventing sand from exiting the filter during backwashing.

Too Much of a Good Thing

While backwashing is essential, it is possible to backwash a sand filter too often or for too long. During backwashing, turn the hose off as soon as the water runs clear. Prolonged backwashing of your sand filter can cause “channeling,” which occurs when channels develop down the sides inside the filter. Water can bypass the sand altogether because of channeling, defeating your sand filter’s purpose.

As with all aspects of your pool’s maintenance and day-to-day operations, please follow your specific sand filter’s instructions carefully. You will likely find directions on the filter itself. Your filter and pump are the backbones of pool cleanliness, safety, and enjoyment, and paying them proper attention is essential. A failure of either will cause problems and cost you money. You should consult a pool professional if you have any pool maintenance concerns.

Frequently Asked Questions About Backwashing a Fiberglass Pool

  1. How do I know when it’s time to backwash my sand filter?

Check the pressure gauge on your filter. When it reads 8–10 psi higher than the clean baseline, it’s time to backwash. Cloudy water can also be a sign your filter needs cleaning.

  1. What is the correct way to backwash a sand filter?

Turn off the pump, set the multiport valve to Backwash, and restart the pump for about two minutes or until the sight glass runs clear. Then turn the pump off, switch the valve to Rinse for 30–60 seconds, and finally return it to Filter mode. Always shut off the system before moving the valve handle. (See the illustrated instructions above)

  1. Can I over-backwash my pool filter?

Yes. Backwashing for too long or too often can cause “channeling,” where water cuts paths through the sand and bypasses filtration. That’s why it’s important to stop once the water in the sight glass runs clear.

  1. Why is backwashing important for fiberglass pools?

Even with fiberglass’s lower maintenance needs, filters still collect debris, sunscreen oils, and fine particles. Backwashing clears these out, helping your system run efficiently, keeping water clear, and protecting your pump from strain.

  1. What if I see sand in my pool after backwashing?

That usually means the filter has broken laterals or too much sand. A proper freeboard (the space between sand and the top of the filter) is needed to prevent sand from escaping. In this case, inspection or repair is necessary.

  1. Do cartridge or DE filters need backwashing too?

No. Cartridge filters should be rinsed or replaced, and DE (diatomaceous earth) filters require backwashing plus recharging with fresh DE powder. Only sand filters use a standard backwashing cycle.

When is the Best Time to Open My Pool?

Posted on by kristin

It’s that time of the year! Spring is finally here! The weather is warming up, and the prime summer swim season is almost upon us. If this is your first season as a pool owner, or you just need an annual refresher, you may wonder when the best time is and what the best practices are for opening your pool. As a manufacturer of fiberglass pools, Thursday Pools does not install or maintain customers’ pools. However, we’re very familiar with pool-opening maintenance based on vast experience working with independent pool dealers, installers, and professionals across the country. 

 

 

The Best Time to Open Your Pool

 

Your pool opening and closing schedule will vary based on where you live. Once you’ve made it past the last dangers of a damaging freeze, it’s time to get ready. The sooner you open your fiberglass inground pool, the sooner you’ll have fun in the sun with all your family and friends.

 

How to Reopen a Fiberglass Pool

 

  1. Check Your Water Level

What is the first thing you should do when opening a pool? You’ll need to check that your water level is up to the midway point on your skimmer before you remove your pool cover. Even with your pool tightly covered, your water level will likely lower over the winter. Groundwater levels are often at their highest in the spring, especially if you have a lot of snow in the winter. If groundwater pressure is unequalized, it can cause catastrophic damage to your fiberglass inground pool.

 

  1. Remove Your Pool Cover

With your water level correct, pump off any water on the pool cover. Be sure to pump away from your pool so you aren’t just adding more groundwater around it. If you have a leaf blower, it might be helpful to blow off any leaves or other debris. After that, the process depends on which kind of pool cover you have:

 

  • Automatic Pool Covers: Your pool opening will be easier if you have an automatic pool cover. Be sure to open it gradually with your touchpad, checking that your cover isn’t sticking or crooked in the tracks as you go. 
  • Standard Winter Covers: Be sure to check your cover’s manufacturer’s instructions for proper removal practices. The cover will require cleaning and sanitation before storing it away for the fall’s pool closing. Removing your pool cover the wrong way can cause unwanted debris to fall into the pool and contaminate your water, adding to maintenance and cleaning needs.

 

 

  1. Check Your Equipment

Once your water is at the proper level and your cover is off, you can turn on and check all your pool equipment. Pumps, filters, filter media, skimmer baskets, and lights sitting idle in the elements all winter might need tuning up or replacing. Before the summer swimming season fully kicks off is the best time to find out something needs attention. Most professional pool opening service providers will perform a complete check and alert you to any problem areas or necessary repairs. If all is working well, leave your pump on and let the water circulate for at least 12 hours.

 

 

  1. Check Your Pool Water Chemistry

After your water has a chance to circulate, test the water chemistry for balance. Water balance can be more challenging at the start of the season. Whether or not you have a pool service pro open your pool, you might need help balancing your water after a long winter. Many swimming pool professionals provide computerized water analysis to test for water balance factors. It’s always a good idea to professionally test your pool water regularly to keep track of the most critical components for safe and healthy water. If you properly balance your water when opening your pool, you’ll have an easier time keeping your water chemistry in balance throughout the swim season. 

 

 

  1. Give the Pool a Spring Cleaning

Ring in the new swim season by giving your pool’s surfaces a good scrub. Be sure to use a soft brush or sponge, and avoid abrasive cleaners that can damage the finish. Next, it’s time to vacuum. Begin in the shallow end and work your way down the slope of the pool. Thoroughly clean around the steps and other crevices where debris can accumulate.

 

 

  1. Inspect Your Safety Equipment and Pool Accessories

Take time in the spring to inspect, maintain, or replace safety equipment, pool accessories, and outdoor furniture so that you can relax with poolside peace of mind on opening day and all summer.

What Does Routine Fiberglass Pool Maintenance Look Like?

Posted on by kristin

Benefits of owning a fiberglass pool include reduced upkeep demands and the guarantee of continuous enjoyment during the warmer months. However, it’s essential to recognize that consistent maintenance efforts are still necessary. Maintaining pool water chemistry is critical to ensure your pool remains a radiant and inviting space to spend time with family and friends. 

 

Starting the Season Right

Opening your fiberglass pool marks the commencement of the swimming season and sets the stage for a season of fun and relaxation. Once you open your pool, commit to conducting daily tests to adjust your pool’s chemistry until the water’s chemistry factors fall within the following ranges:

  • pH: 7.2 to 7.4
  • Total Alkalinity (TA): 80 to 120 ppm
  • Cyanuric Acid (CYA): 30 to 50 ppm
  • Calcium Hardness (CH): Less than 120 ppm (do not add calcium)
  • Total Dissolved Solids (TDS): Less than 1,500 ppm (or up to 1,000 ppm above your salt level)

 

This crucial first step ensures your pool water is neither too corrosive nor scaling, protecting the integrity and appearance of the fiberglass gel coat.

 

Maintaining Chlorine Levels

Once your fiberglass pool’s other water chemistry factors are within the recommended ranges, adding sanitizer maintains chlorine levels within a safe range of 1 to 3 parts per million (ppm), optimal for disinfecting the pool without damaging the fiberglass surface. Monitoring and adjusting chlorine levels is a fundamental aspect of routine maintenance that keeps the water clear, clean, and safe for swimmers.

 

 

Weekly Checks and Adjustments

Your pool’s water chemistry can quickly fluctuate even after establishing a balanced baseline due to various events such as changes in swimmer load, weather conditions, organic debris, water evaporation, and more. Perform weekly tests to monitor water chemistry, checking the chlorine, pH, alkalinity, and other factors are within recommended ranges. These regular check-ins help catch and correct minor imbalances before they become bigger issues.

 

 

Water Level and Filtration Maintenance

Maintaining the pool’s water level is another vital aspect of routine care. The water level should always be halfway to the top of the skimmer window to ensure efficient filtration and circulation. Regularly check and clean the filter and skimmer baskets to prevent clogs and maintain proper function. Vacuuming your pool to remove debris and sediment keeps the water clearer and reduces the strain on your pool’s filtration system.

 

 

Gentle Cleaning for Long-Lasting Shine

The non-porous gelcoat surface of fiberglass pools is highly stain-resistant, making cleaning a breeze. A soft microfiber cloth, sponge, or pool brush with nylon bristles should suffice. Some household cleaners contain harsh chemicals unsuitable for fiberglass pool surfaces and may cause damage over time. Always use cleaners specifically designed for fiberglass pools, as aggressive cleaning agents can damage the gelcoat, leading to unnecessary wear and repair costs. Metal scrapers or putty knives can gouge or scratch the fiberglass when used to remove debris or scale. Avoid using highly abrasive tools such as wire and stiff-bristle brushes or steel wool. 

 

 

The Value of Prevention

In pool maintenance, an ounce of prevention is worth a pound of cure. Regular, proactive care keeps your pool looking and performing its best and extends the life of your investment. Fortunately, the inherent durability and ease of care with fiberglass pools mean that maintaining balanced water chemistry requires less effort than you might think. Test kits and resources such as the Thursday Pools Fiberglass Pool Care Guide can help quickly provide direction on how to balance your pool water best.

 

Understanding Low Maintenance Isn’t Maintenance-Free

While we celebrate fiberglass pools for their low maintenance needs, it’s important to remember that “less maintenance” doesn’t mean “maintenance-free.” The foundation of a healthy, long-lasting pool is achieving balanced water chemistry through frequent and routine testing, precise adjustments, and regular cleaning. By embracing these responsibilities, you’ll ensure your pool remains a beautiful source of joy, relaxation, and pride.

Five Essential Steps to Maintain Your Pool’s Finish

Posted on by kristin

For many homeowners, the benefit of reduced maintenance responsibilities is influential in their decision to install a fiberglass pool in their backyard. The non-porous surface of a fiberglass pool significantly lessens the likelihood of algae growth and reduces the demand for chemicals to maintain water balance. This inherent characteristic of fiberglass pools substantially contributes to their appeal, offering homeowners more time to enjoy their aquatic sanctuary with less laborious upkeep. However, it’s crucial to understand that “lower maintenance” does not equate to “maintenance-free.” Maintaining your pool’s vibrant, smooth finish is just as important as keeping the water clear and inviting. While the allure of crystal-clear water is undeniable, the unseen balance of water chemistry plays a crucial role in preserving the integrity and appearance of your pool. 

 

Step 1: Use a Stain and Scale Control Product Regularly

 

Even well-balanced water can carry minerals that deposit on your pool’s surface, leading to staining or scale buildup. A reliable stain and scale control product helps prevent fiberglass pool discoloration with chelating agents that can effectively shield your pool from calcium. In our experience, products like SC-1000 by Orenda and Scale & Stain Eliminator by Pool Stain Removers work well and should be part of your regular pool maintenance routine.

 

Step 2: Maintain Chlorine Levels Between 1-3 ppm

 

Chlorine protects your pool from harmful bacteria and algae. While chlorine is essential, too much can harm your pool’s finish. Keep free chlorine between 1 and 3 ppm. Beware of exceeding 5 ppm, as high chlorine levels can cause irreversible damage to your pool’s surface, leading to discoloration and degradation of the gelcoat.

 

Step 3: Avoid Calcium Hypochlorite

 

While calcium hypochlorite is common in various pool contexts for shock treatments, it poses risks for fiberglass pool surfaces due to its propensity to elevate pH levels and deliver a high dose of free chlorine. Liquid chlorine is a preferable alternative, offering a safer means to manage pool hygiene without the associated risks of calcium hypochlorite. Nevertheless, vigilance is required to prevent the adverse effects of excessive chlorine, ensuring the pool’s surface remains pristine.

 

Step 4: Keep pH Between 7.2 and 7.4

 

Maintaining a pH range between 7.2 and 7.4 keeps your chlorine effective and protects the pool’s surface. A pH above 7.8 can contribute to scaling and discoloration, while a pH that’s too low can lead to etching. Regular testing and adjustments help keep this critical pool maintenance parameter within range.

 

Step 5: Maintain Calcium Hardness Below 120 ppm

 

Fiberglass pools don’t need the same high calcium levels as concrete pools. Keeping calcium hardness less than 120 ppm helps prevent scale buildup and maintains the beauty of your surface finish. Do not add calcium-based products. If your water’s calcium hardness is greater than 120 ppm, use a chelating stain and scale control product to prevent scaling and discoloration.

 

Bonus Tip: Don’t Assume Your Pool Pros Know it All!

 

The pool maintenance industry is constantly evolving, with new products and refined best practices emerging regularly. As a pool owner, staying informed about these developments is beneficial to ensure your pool receives the best care possible.

 

Engage with your pool maintenance professionals and inquire whether they are familiar with specific parameters for fiberglass pools. Fiberglass pools are unique, and maintenance pros should treat them as such.

 

By following these five essential tips and staying on top of your water chemistry, you’ll protect your pool’s beauty and performance for years to come. Pool ownership is a journey. When you have the right knowledge, it’s a journey you can enjoy with confidence.

Should I rely on a pool service professional for water balance?

Stay informed and ask questions. Fiberglass pools require specific care, and not every pool professional knows the latest best practices. Double-check your pool’s water chemistry balance yourself regularly.

Examining the Elements Involved in Factoring LSI

Posted on by kristin

Maintaining balanced pool water chemistry in your fiberglass pool is truly a balancing act. Each of the six factors that calculate the Langelier Saturation Index (LSI) can ebb and flow, although some are more reactionary and volatile than others. While maintaining all six factors may feel like a juggling act, understanding what they are, how they interact, and their impact on your pool is critical to keeping the LSI balanced and your water in equilibrium.

 

The Critical Role of pH

pH, or “potential of hydrogen,” is the most critical variable in water chemistry balance. While alterations of any involved equation variables can affect your water balance, a change in pH can have ten times the effect compared to other LSI factors. 

pH levels indicate water’s acidity or basicity. They range from 0 to 14, with 0 being very acidic, 7 being neutral, and 14 being very basic. Chlorine and other sanitizers will only remain effective and function correctly within specific pH ranges—namely, the range between 7.2 and 7.4 deemed ideal for swimming pools. Hydrochloric or muriatic acid can lower high pH levels, while a low-pH pool will need an alkaline boost from sodium carbonate. 

The best thing an owner can do for the health and safety of their pool and its frequent swimmers is to regularly test the pH and other chemical levels. Daily testing and checks before and after each use are recommended and will help you become more familiar with how various factors, including some outside your control, affect your pH and overall LSI levels. 

 

Total Alkalinity

Alkalinity is often called “the yin to pH’s yang,” as the two are related. Alkalinity measures water’s capacity to withstand changes in pH. In fiberglass pools, recommended total alkalinity levels range from 80 to 120 parts per million.

Low alkalinity makes water corrosive, causing stains and etching on your pool’s surface. Water will become depository if alkalinity rises above the recommended range for fiberglass pools (120 ppm). As a result, pool surface scaling occurs and a white cloudy film may appear, clogging filters and reducing circulation.

 

Total Dissolved Solids (TDS)

As the name implies, total dissolved solids (TDS) include chemicals or anything other than calcium that remains after water evaporates. These solids can include salts, metals, minerals, and other organic materials that have entered and dissolved within the pool water. We recommend that the TDS level be no higher than 1,500 ppm (or 1,000 ppm above safe salt level in saltwater pools). A high TDS level can lead to algae blooms, scaling, or other pool stains.

 

Cyanuric Acid (Chlorine Stabilizer)

Cyanuric acid (CYA) will prevent the sun’s ultraviolet rays from decomposing free chlorine in your pool water. Levels between 30 and 50 ppm are recommended, but higher levels don’t necessarily mean better results. If the cyanuric acid level reaches 100 ppm or above, chlorine’s effectiveness at killing bacteria and algae is compromised.

 

Calcium Hardness

A lower calcium hardness level in your pool water results in a softer and silkier it will feel on swimmers’ skin. Calcium hardness is also essential for maintaining water cleanliness and equipment operation. Regulated calcium hardness of less than 120 ppm will help keep pool materials looking and working their best. When calcium hardness is too low, the water becomes aggressive and corrosive. When too high, pH levels raise, leading to cloudy water, surface discoloration, and filter-clogging calcium deposits.

 

Temperature

The temperature factor is the only non-chemical component of water chemistry balance and your pool’s LSI. Utilizing a pool heater will make your temperature factor much easier to control. Many swimmers enjoy a “bathwater” feel and temperature, but water warmer than 82 degrees Fahrenheit can encourage bacteria or algae growth. Calcium deposits form more quickly in warmer water, while a too-cool pool makes it easier for water to begin corroding equipment.

Parents of infants and young children should consider keeping temperatures slightly higher into the upper 80s. However, a pool used primarily for exercise or competitive swim training should skew lower, between 77 and 82 degrees Fahrenheit. A good general rule for many pool owners is aiming for a water temperature between 77 degrees and the mid-80s. Keeping a constant temperature will help prevent bacteria and algae growth and improve the efforts of chlorine, saltwater, or other pool sanitation measures.

 

Every Factor is Important

Many pool owners and even pool service professionals habitually test for pH and chlorine, and occasionally they check the alkalinity. However, this approach ignores many critical LSI factors. Although they do not tend to change as rapidly, You should also regularly test calcium hardness, CYA, and TDS. By testing all six factors in your pool water, you will have a more clear and complete understanding of its LSI and water balance.

 

How Do I Balance My Pool Water Using LSI?

Posted on by kristin

Balancing your pool water is essential for maintaining its clarity, safety, and longevity, especially for fiberglass pool owners. While pool water chemistry balance may seem complex, modern tools like the Orenda Technologies LSI Calculator have simplified the testing and adjustment process. This blog post will guide you through using Orenda’s app to achieve optimal water balance in your pool, ensuring it stays in beautiful condition without needing a degree in chemistry. We’ve included step-by-step instructions, complemented by screen-capture images, to make the process as straightforward as possible.

Editor’s Note: There are available alternatives to the Orenda app. Thursday Pools and Orenda have no relationship other than sharing a desire to help fiberglass pool owners properly maintain their water chemistry. If you want to get even more informed on water balance and related topics, check out Orenda’s library of educational videos, tutorials, and other resources. 

Step 1: Download the Orenda App

The journey to balanced pool water begins with a simple download of the Orenda app, available on both iOS and Android platforms. This app significantly simplifies pool chemistry, particularly focusing on the Langelier Saturation Index (LSI), making it an indispensable tool for pool owners.

Step 2: Input Your Pool Details

Once you have downloaded and opened the app, the first step is to input your pool’s specific details, such as the volume of your pool in gallons and the water temperature, which are critical for accurate calculations. The app’s user-friendly interface guides you through entering these initial details.

 

Step 3: Enter Current Water Chemistry Levels

The next step involves inputting the current levels of various water chemistry variables that influence your pool’s LSI.

Water Chemistry Levels

These include: 

  • Water temperature
  • pH level
  • Calcium Hardness
  • Total Alkalinity
  • Cyanuric Acid stabilizer
  • Total Dissolved Solids

You’ll find a section on the left-hand side of the app dedicated to entering these values. Precise measurements at this stage are crucial for accurately assessing your pool’s water balance. 

Also, note that the app includes levels for Chlorine and Phosphates. While these values don’t affect the LSI, they are essential in maintaining a healthy and safe pool.

 

Step 4: Adjusting for Optimal LSI

After entering your pool’s details and current chemistry levels, the real magic begins. The app allows you to tweak and adjust the values on the right-hand side of the screen to see how changes can affect your pool’s LSI. 

The goal is to adjust these levels until you achieve a desired LSI value within the optimal range of -0.3 to +0.3. Note that for saltwater pools, we recommend a slightly tighter range of -0.2 to +0.2 to account for the unique chemistry of saltwater systems.

Optimal LSI

The app’s LSI indicator is highlighted in different colors depending on the status. 

  •   Over +0.30 is coded PURPLE, meaning your water can cause scaling on your equipment and gelcoat surface. 
  • -0.30 to +0.30 is coded GREEN to indicate the ideal LSI balance. 
  • -0.30 to -0.01 is YELLOW, meaning you’re close to balance but not quite there. 
  • < -0.30 is coded RED to alert you to corrosive water that can damage your pool equipment and gelcoat surface.

The ideal target is as close to zero as possible. This interactive feature allows you to experiment with different adjustments to understand how each factor may affect your pool’s overall balance.
