Why is my fiberglass pool’s shell dulling? This is a frequent concern that fiberglass pool customers may have to face at some point.
This whitening can start as a white material forming on the walls of the pool and can also make the water appear cloudy. The white particulate can also build up in the filter which will require constant cleaning. This can happen to any fiberglass pool because of age, excessive chemical treatments (especially overchlorination) or more frequently, a combination of these issues.
If you view a layer of white or greyish-white material on the sides of your pool around the tile line, that’s calcium. Calcium can build up and leach into the pool’s gelcoat. As fiberglass pools begin to get older the gelcoat finish will slowly fade to white over time. Calcium scale deposits happen when your water an over abundance of calcium or from hard water. The white flakes are typically from calcium deposits that have accumulated over the years.
Maintaining a beautiful fiberglass pool requires keeping the water in balance by keeping the right chemicals and systems to help eliminate the processes that make calcification occur. One such system is the Vibranz fiberglass pool care system.
