Phosphate removers can also goop up your pool, making your water cloudy. We have never had (in my memory) an occasion where a pool owner needed them, and we have people with perfectly clean, sanitary pools that have phosphate levels that make pool stores salivate at how much remover they THINK they will sell. I think Chem_Geek has a phosphate level of 3000, and 500 is "too high". His pool is as clean as anybody's. Why? He uses the B-B-B method rigorously.
