Why is my fiberglass pool shell whitening? This is a common concern that fiberglass pool customers may have to face at some point.
This dulling can start as a white film forming on the shell of the swimming pool and can also make the water appear 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 commonly, a combination of these concerns.
If you see a film of white or greyish-white grime on the walls of your pool around the waterline, that’s calcium. Calcium can build up and leach into the pool’s gelcoat. As fiberglass pools begin to age the gelcoat or color will slowly fade to white over time. Calcium scale deposits occur when your water has too much calcium or from hard water. The white metal depostis are typically are there from calcium deposits that have built up over time.
Keeping a great looking fiberglass pool means keeping the water in balance by keeping the right chemicals and systems to help eliminate the factors that make calcification possible. One such system is the Vibranz fiberglass pool care system.
