If your pool is clear, no sign of algae, with YOUR numbers you can and should stop wasting your money on phosphate removal. Phosphates are food for algae, no more. Many of us have fairly high phosphate levels (if we bother to test for it at all--I never have) and STILL have perfectly clean and sanitary pools. Phosphate removal DOES have a legitimate place in pool care, but not for 99.99% of us. It's just another revenue-generating scheme.

Furthermore, we've found that in the rare case where it's appropriate (persistent, tough mustard algae) the EFFECTIVE level of phosphates is far, far lower than the levels the pool stores tell you.
