Why is my fiberglass pool shell whitening? This is a common concern that fiberglass pool owners may have to understand 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 particulate can also build up in the filter which will require frequent cleaning. This can happen to any fiberglass pool because of age, excessive chemical treatments (especially overchlorination) or most frequently, a combination of these issues.
If you see 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 age the gelcoat finish will slowly fade in color over time. Calcium scale deposits happen when your water an over abundance of calcium or from hard water. The white metal depostis are usually from calcium deposits that have accumulated over time.
Maintaining a great looking fiberglass swimming pool means keeping the water in balance by saturating it with the right chemicals and systems to help control the processes that make calcification possible. One such platform is the Vibranz fiberglass pool care system.
