Still having a problem holding chlorine in my pool. I had my water tested at a different store and they checked for phosphates and said my phospahte level was really high (above 2500 ppb). What is the best way to get rid of this problem? I found stuff called Phosfree and PhosPhloc which is supposed to solve this problem. Is this the best way to go and how is it used in my pool.
Thanks in advance for any suggestions.
