In a pool with a salt chlorine generator, it is important to be diligent about keeping phosphate levels down. The following are some guidelines that can help.
• Test water for phosphates on a weekly basis;
• Treat the pool weekly with a phosphate remover;
• Use only non-phosphate metal products and cleaners;
• Clean and remove grass, leaves and any organic debris from the pool as quickly as possible;
• Test tap water (i.e. source water) to determine phosphate levels; and
• Test for and treat phosphates after any periods of extreme weather or heavy swimming.
