    Acid

    I need to lower my pH (it is reading at 7.8)

    Is hydrochloric acid the same thing as muriatic acid?

    Re: Acid

    Thank you! I went to Home Depot to buy muriatic acid and came home and noticed it said hydrochloric acid. Thought I goofed.

    Thanks again!

    Note that there are two different strengths. 31.45 % is the full strength and usually the better deal.

    When using the pool calculator, it's important to select the strength you are using.

    Re: Acid

    I checked and have the 31.45% strength. I will double check before adding.

    Re: Acid

    I finally had to ask someone where it was. It was in Outside Garden and was as far away from everything as possible. It came in a cardboard box (2 per box).
