After trying to battle cloudy water for two days with obscene amounts of chlorine, I got my water tested today. All of the chemical levels are normal except the pH, but he said I have an extremely high level of phosphates (>2500).

He had a product there, but had just gotten it in and didn't know what it costs yet. He said to shock it again and if that didn't help, and it probably wouldn't, to check back in a few days.

Are there any grocery store items that can be used to combat phosphates?

My numbers are...
TA 100
pH 6.6
CYA 30
TH 90
TC 1.9
FC 1.9
