I started maintaining my own pool using the BBB method a few months ago when we fired our pool guy and the pool has never looked better. My problem is rising pH, likely due to the spa overflowing into the pool. Here are this morning's numbers:
Water temp: 86 F
I keep a floater with a trichlor puck in the pool to maintain chlorine levels. It is just me and my wife and we swim on the weekends, so the pool sees no use during the week. We live in S Florida and the afternoon thundershowers fill the pool regularly, which I drain to maintain an appropriate level, so there is a lot of new rain water being added regularly. The pH always seemed to rise when I had my Total Alkalinity at 80-100. and I was adding a lot of acid. I recently lowered TA to 40 and it rose to 50 in the past few days, I assume due to rain water. According to the Pool Calculator, my CSI is -0.48, not lower than -0.6, but close. Just want to be sure I am on the right path to keeping my pH in check. Obviously I will continue monitoring the TA for the next few weeks and see if it goes back up. Thanks!
