3 Key Maintenance Issues with Fiberglass Pools

fiberglass pool maintenanceWhile fiberglass pools are not maintenance-free compared to other pool types, they do require the lowest maintenance. Over the course of their lifetimes, vinyl pools will require several liner replacements, and gunite pools will need to be resurfaced every four to six years. Fiberglass pool shells can last a lifetime, but owners will still need to perform regular fiberglass pool maintenance to ensure they stay beautiful.


Let’s take a look at a few maintenance issues every fiberglass pool owner should be aware of. 


  • Maintaining balanced water chemistry. Maintaining balance water chemistry is key to ensuring your pool water is safe and healthy for your family. It’s also crucial to protecting your fiberglass pool investment. Unbalanced water can be harmful to your fiberglass pool’s surface and to your automatic safety cover, handrails, heater and other swimming pool equipment.


Crystal clear water does not necessarily mean balanced water. Regardless of the type of pool you have, you should test your water chemistry levels regularly, record them at least once a week and adjust as needed to achieve proper water balance. If you have trouble maintaining your water chemistry, you may need to hire a pool maintenance pro to get your water where it needs to be. Once it’s back on track, you may be able to more easily keep it balanced on your own. 


  • Keeping your water line clean. Fiberglass pool owners need to be especially vigilant about caring for the water line around their pools’ perimeters. This is the area where body oils, suntan lotions, dirt, and airborne contaminants can build up on the pool surface. Left untended, these materials can leave permanent stains on your fiberglass pool’s gel coat finish. Wipe your water line down on a weekly basis with a soft cloth and a mild detergent as recommended by your pool’s manufacturer.


While gunite pool maintenance requires steel brushes and plenty of elbow grease, fiberglass pool maintenance is quite the opposite. You should never use abrasive cleaners, automatic dish detergent, steel wool, metal scrapers or other rough brushes or tools because they can cause permanent damage to the gel coat finish of the fiberglass pool. 


  • Maintaining proper groundwater pressure. Equalizing groundwater pressure is crucial for every type of pool. The simplest way to do this is to keep your water level even with your skimmer, whether your pool is open or closed. If groundwater pressure is not properly maintained, a fiberglass pool can float in the ground. However, with innovative options, such as the Fiberglass Pool Geo-Anchoring System, fiberglass pool walls resist movement or bulging, and provide the strongest fiberglass pool construction available on the market today.
