Thread: lowering TA

    lowering TA

    I just converted to swg pool. Chlorine is great however my TA is 110 (s/b 60-80) and my pH is 7.2. Should I lower my pH below 7.0 and then us air to raise pH back up or will lowering to 7.0 be enough?

    You should only lower the pH down to 7.0-7.2 and then aerate to raise it back up.

    You can just wait and the pH will rise on its own as the TA is high. Once you are not adding CYA just let the SWG run and pH will drift up on its own.
