    What is sodium bisulfate ?

    Very new to this and I'm trying to lower my ph. My husband bought this what is it? I couldnt find it on the pool calculator. Will it work or should I just get baking soda.

    Dry acid and yes it is used to lower the pH.

    You would not use baking soda to lower pH. Use baking soda to raise TA.

    Most people on here would recommend muriatic acid to lower pH because the sodium bisulfate addes sulfites to the water which can damage concrete over time.
