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.
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.
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.
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.
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.
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.
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.
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.
The Thursday Pools Fiberglass Pool Care Guide is your resource for the Top 5 Tips for Maintaining Your Pool Finish.
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.
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?
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.

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.
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)
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.
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.
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.
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.
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
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.
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:
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.
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.
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.
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.

Open your pool once the risk of hard freezes has passed. Opening early gives you more time to enjoy the season and makes water chemistry adjustments easier before the pool is in heavy use.
Yes. If evaporation has lowered the water level over the winter, make sure it’s back to the midpoint of the skimmer before uncovering to protect the shell and ensure proper circulation.
First, pump away standing water and clear debris with a blower or broom. Carefully follow your cover manufacturer’s instructions to avoid dumping dirty water and leaves into the pool.
Inspect your pump, filter, skimmer baskets, and lights for any signs of wear, leaks, or damage. If everything appears in good condition, start the system and let the pump run at least 12 hours to circulate the water. If you see problems, call a pool professional before operating the equipment.
Even if your pool was winterized correctly, chemistry shifts over months of inactivity. Testing and adjusting pH, chlorine, alkalinity, calcium, and CYA right away prevents staining or scaling and makes water easier to maintain all season.
As the vibrant days of summer fade into the crisp air of autumn, fiberglass pool owners face the critical task of preparing their pools for the off-season. However, the upcoming period of dormancy does not equate to a halt in maintenance efforts. Instead, the off-season requires a strategic approach to ensure your pool water is neither corrosive nor scaling and will be ready for the next swimming season. Smart homeowners must understand the essential steps for monitoring the pool’s water chemistry balance during the colder months to safeguard against potential damage that winter can bring.
Fiberglass pools, celebrated for their durability and longevity, are not immune to all the challenges of changing seasons. Fiberglass pool shells are generally resilient against winter conditions thanks to their flexibility, which can withstand stress from freezing temperatures. However, harsh winter conditions can still threaten the water balance and the pool surface if you do not properly winterize the pool. The risk of damage escalates during winter when colder water temperatures can render the water more aggressive. This aggressiveness primarily stems from the water’s chemistry balance shifting with temperature changes, potentially leading to issues that can compromise the integrity of your pool’s finish.
The first step in your off-season maintenance routine should be thoroughly cleaning your pool. End-of-season cleaning includes wiping down the waterline with a soft brush to eliminate any buildup of debris, sunscreen, body oils, and other contaminants that may have accumulated over the swimming season. Brush all pool surfaces, paying extra attention to corners and steps where algae and bacteria might accumulate. Remove all leaves, debris, and dirt from the water using a skimmer, and vacuum the pool thoroughly to eliminate any settled particles or algae. A clean pool goes beyond attractive aesthetics to create a stable foundation for your off-season water balance efforts.
Investing in a high-quality pool cover offers multiple benefits throughout the year, with its importance magnified during the off-season. A pool cover acts as a barrier against debris, reduces water evaporation, and helps maintain the pool’s water chemistry balance by minimizing external influences.
Especially important for households with children or pets, a properly secured winter pool cover can also prevent accidental falls into the pool. Safety covers can withstand a person’s weight, providing an extra layer of protection when the pool is not in use. More than a convenience, a pool cover offers peace of mind and ensures your pool remains clean, sealed, and safe throughout the winter.
The effort you put into off-season maintenance directly impacts the longevity and condition of your fiberglass pool. By taking steps to clean your pool, adjust its water chemistry for the cold, periodically check its balance, and secure it with a pool cover, you protect your investment and make for an easier and more efficient opening in the spring.
A proactive approach ensures your pool remains a source of enjoyment and relaxation for many years without extensive repairs or adjustments when the swim season arrives. Embrace the off-season as an opportunity to ensure your fiberglass pool’s continued health, beauty, and enjoyment.
Cold water can shift your pool’s chemistry and become more aggressive. Keeping pH, total alkalinity, and calcium in check, and routine use of a stain and scale product, helps protect your fiberglass surface and equipment throughout the winter months.
Yes. A thorough cleaning is essential. Brush all surfaces, skim, and vacuum to eliminate algae, dirt, and debris. A clean pool sets the stage for stable water chemistry all winter long.
A high-quality pool cover keeps debris, dirt, and leaves out of the water, reduces evaporation, and helps preserve your pool’s chemical balance. Covers make winter care easier and spring openings faster.
Yes. Weather permitting, check the water’s balance periodically. Cold water’s chemistry can still shift over time, and making small adjustments ensures it remains stable. Regular checks prevent surprises at spring opening and help extend the life and beauty of your fiberglass pool.
The biggest mistakes include failing to balance water chemistry for colder temperatures, skipping a thorough cleaning before closing, and not using a quality pool cover. Neglecting these steps can lead to algae growth, staining, scaling, or corrosion that makes spring opening more difficult and costly.
When you clean, balance, and cover your pool correctly before winter, you prevent debris buildup and chemical imbalances. That means fewer surprises—like cloudy water, stains, or equipment issues—when you reopen. A proactive approach saves time, reduces costs, and helps you start swimming sooner in the spring.
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:
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.

Test your pool daily when you first open it for the season until the critical water chemistry factors remain within the recommended ranges. After that, weekly tests help keep chlorine, pH, and alkalinity levels in check.
Keep free chlorine between 1 and 3 ppm. This range keeps the water safe and sparkling without damaging the fiberglass gelcoat.
Use a soft microfiber cloth, sponge, or a nylon-bristle pool brush. Avoid harsh chemicals, stiff brushes, or metal tools that can scratch or damage the gelcoat.
Keep the water level halfway up the skimmer window to ensure the filtration system runs efficiently and helps prevent pump and skimming issues.
Yes, it is widely accepted in the pool industry that fiberglass pools are lower maintenance than other pool types. However, “less maintenance” doesn’t mean “maintenance-free.” Fiberglass pools resist algae and staining, so they require fewer chemicals and less scrubbing, but you still need regular testing, cleaning, and filter care to maintain your pool’s aesthetic and longevity.
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.
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.
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.
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.
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.
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.
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.
