Due to excessive calcium scaling and staining, I drained and acid washed my pool approx 3 weeks ago. I test my water daily with the TF 100 and do additions according to the Pool Calculator. My TA out of the tap was 180 and it took close to two weeks to get it to 80. Due to the hardness of water in PS, my goal is to keep my pH below 7.4 to ensure the staining doesn't repeat. However, my pH rises .3-.4 daily, here are the current numbers
pH yesterday after acid addition 7.3, today 7.6
Any advice would be appreciated, thanks for all of the help!
