Our pool (40,000 gallon, cement, stainless steel, in ground) has been cloudy for about 5 days. I took the water to the pool store on Friday. The water test was:

FAC .5
TAC 5

PH 7.3

TA 170

Cyanuric Acid 30

Phosphates 2500

The phosphates have been high all season and I have been adding phosFree every week (with really no results)

I added Fresh and Clear Oxidizing Shock (Potassium peroxymonosulfate 38%) on Friday. It did not get any better (4 pounds total). I added Fresh and Clear again (4 pounds total) today.

The pool store says its Chlorine lock but my CYA isn't high.

Suggestions?????

Thank you!!!
