Why is my fiberglass pool shell fading? This is a common question that fiberglass pool customers may have to face at some point.
This dulling can start as a white film forming on the walls of the pool and can also make the water seem hazy. The white film 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 commonly, a combination of these concerns.
If you see a layer of white or greyish-white material on the walls 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 in color over time. Calcium scale deposits occur when your water an over abundance of calcium or from hard water. The white metal depostis are typically are there from calcium deposits that have accumulated over the years.
Keeping a beautiful fiberglass swimming pool requires keeping the water in balance by saturating it with the right chemicals and systems to help control the factors that make calcification possible. One such system is the Vibranz fiberglass pool care system.
