After having an algae /cloudy pool problem almost all summer, I have finally used pool school to start getting ahead of the problem. Thanks to this site as I was about to give up on the pool and take it down for good. The question I have is that I am lowering TA from 100 to the recommended 60-80 for a SWG pool. I read in the SWG pool chemistry section that this is important. I was just wondering what causes high TA to be a bad thing. Could it inhibit Cl production or limit its effectiveness. Just wondering. Thanks for the replies.
