    controlling ph rise from aeration

    Hey guys as always thanks in advance. I'm wondering if there is a trick to stopping the ph rise that is coming from the 2 spillovers coming from the spa into the pool and the infinity edge. We also have an infinity edge that is about 17 linear feet. I would like to run the infinity edge daily to act as skimmer but not if it is going to kill my ph. Any options or does this just come with the features?

    What is your current TA level? Lowering ta to 60 or even 50 can help Borates will also help slow PH rise.

    Ph was 7.9
    Ta was 120

    I was going to pour some muriatic acid in bit didn't get a chance. If I'm going to order some chemicals, what would you suggest so I'm not going through so much acid?

    In addition to a lower TA, you can use a higher pH (Depending on the calcium hardness and cyanuric acid levels and the water temperature).

    Start with Muratic Acid, available from big box stores like Lowes and Home Depot.

    Use the Pool Calculator to determine how much to add. Target 7.2 on your PH, and everytime the PH rises to 7.8 or higher, lower it to 7.2 with acid. Eventually the TA will drop down into range (60-70) and the PH drift should be reduced significantly.
