Hi to everyone and thank you for your great advice. I was given a Crestwood (wooden side) pool last year and thanks to the advice on this forum I was able to level and erect an 18' round AG pool and my kids absolutly LOVE it. My problem is this, over the winter I noticed a slit in the winter cover but could do nothing about it because in Northeast PA the pool was frozen solid. In the spring, l eventually brought it back from green, now the water is fairly clear (I can see the bottom well) but it just does not sparkle like it did last year when I got the water delivery. FC =4, pH=7.5 cya=50 TA=100. I do not want to get "pool stored" but what is "clarifier"? It sounds like something that would help me, but what does it really do?

Thank you again for all the help.
