just started our new pool about 2 weeks ago, my CYA is under 20 using a TFP-100 pool kit.... I have read a lot on the forum... and from what I read CYA can be purchased at walmart , lowes, HD, etc... but I am at a lose and don't know exactly how it looks like, can anyone post a pic or a link to what kind of granular CYA you are buying please... thanks in advance...
