Why is my fiberglass pool shell whitening? This is a frequent concern that fiberglass pool customers may have to deal with at some point.
This dulling can start as a white film forming on the walls of the swimming pool and can also make the water seem hazy. 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 commonly, a combination of these concerns.
If you view a layer of white or greyish-white material on the sides of your pool around the waterline, that’s calcium. Calcium can build up and leach into the shell’s gelcoat. As fiberglass pools begin to age the gelcoat finish will slowly fade to white over time. Calcium scale deposits occur when your water has too much calcium or from metals in the water. The white flakes 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 eliminate the factors that make calcification occur. One such platform is the Vibranz fiberglass pool care system.
