Iv'e been reading alot the last couple of days and learned alot. I just did a drain clean and refill on my 5 year old pool and this site answered almost every question I had without me even posting. I got my water right in there where it needs to be according to the fancy computer tester from my local dealer who installed the pool.
My question is really quiet simple , I've been using the shock bags from walmart once a week for years, after reading and learning here I find I can use plain bleech( I did not know that) question: 6000 gallon pool how much bleech each week to shock? Thanks, Joe.
