Why is my fiberglass pool shell fading? This is a common question that fiberglass pool owners may have to deal with at some point.
This fading can start as a white film forming on the shell 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 frequent cleaning. This can happen to any fiberglass pool because of age, over doing 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 walls 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 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 metals in the water. The white flakes are usually from calcium deposits that have built up over time.
Maintaining a great looking fiberglass swimming pool means keeping the water in balance by keeping the right chemicals and systems to help control the processes that make calcification occur. One such system is the Vibranz fiberglass pool care system.
