First I'd like to say Thank You to everyone in this forum. This is my first year with a pool, and thanks to the BBB method it's been clear and algae free all summer. My question is, can some sources of liquid chlorine cause TA to rise? I read this on another thread, due to lye in the chlorine. I started the season using pucks and my levels didn't move much. I know tri-chlor lowers PH and TA, which I adjusted accordingly and LQ raises PH until it burns off then it comes back down, which is exactly what happened. Beginning in July I started using 12.5% LQ I got at BJ's in gallon bottles, and my TA rose 20ppm in a week. I brought it down with acid and aeration. Then I found a place that sells 12.5%LQ in 5ga.carboys, fresh deliveries everyday. After using this LQ my TA didn't move at all for over a month. Last week I started using the leftover LQ I still had from BJ's and the TA rose 20ppm again within a week. The levels are still within range but I'm curious, could that be cause of why this is happening? Thanks.
