Why are phosphates bad for hot tubs and swimming pools?

Phosphates are import contributors to algae growth (essentially food for algae) and can reduce the effectiveness of some automatic chlorine systems. A hot tub or pool with high phosphate levels will have reduced chlorine efficiency.

What level should phosphates be in a hot tub or swimming pool?

Keep phosphates below 300ppb to avoid problems in your pool or hot tub.
