How do you get white scale off a fiberglass pool

Why is my fiberglass pool’s shell whitening? This is a frequent concern that fiberglass pool owners may have to understand at some point.

This whitening can start as a white material forming on the walls of the pool and can also make the water appear 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, over doing chemical treatments (especially overchlorination) or most commonly, a combination of these concerns.

If you see a film 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 shell’s gelcoat. As fiberglass swimming 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 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 eliminate the processes that make calcification occur. One such system is the Vibranz fiberglass pool care system.
