Hi everyone,

Looking for some advice with stains in my plaster pool. I've seen similar stains in previous years, but usually they clear up long before the water is clear. This time around the water is looking good but the stains haven't made much progress. Any thoughts on what they are from or what I should to do clear them up? I have not done an OFCLT yet so maybe this question is irrelevant, but if the overnight test passes should I keep SLAMing? Thanks for the help!

Make a paste with some Vitamin C tablets, put it on a sock, and rub it on the stains. If they lift they area iron stains.

Otherwise try...
