    Cyanuric acid and borax

    I may know the answer to this question, but I gotta ask anyway. Can I use Borax as a conditioner and to adjust the Ph or do I need to buy cyanuric acid as well. Thanks.

    Re: Cyanuric acid and borax

    Cyanuric acid's prime purpose is as a stabilizer and does not have much effect on pH. Muratic acid is the usual product used in conjunction with borax. Borax is typically used as a buffer, a mild algaecide, and to some improves the feel & "sparkle" of the water (due probably to lower water surface tension).

    I would consider the use of borax to accomplish the above functions as secondary purposes. It's primary function as we use it in our pools is to raise pH.

    I think I was addressing the conditioner question and missed the main point. Thanks for bringing it back on track.

    Re: Cyanuric acid and borax

    Thanks for the words of advice. Still not clear on one point though. Can I use borax to raise the Ph level,(which I need to do), and to help stabilize the chlorine?

    Borax pretty much ONLY raises pH (and TA a little) but does nothing to stabilize the chlorine. CYA is what you use for that.

    Re: Cyanuric acid and borax

    Borates at 30-50ppm help stabilize (or buffer) pH. Maybe this is what you were confused by. This is the secondary effetc that was mentioned.
