    ph decreaser

    Can i use ph decreaser that is made for spas? I bought it by accident. It says its 91% sodium bisulfate but it also contains mineral crystals. Also when i go to put it in the pool calculator what percentage is it for me to determine how much to put in. Do i just follow the directions on the back which state for 800 gallons and a ph of 7.6 to 7.8 you add 1.5 tsp. I have an intex 12 ft pool with approx 1900 gallons and i run the filter 24/7 that came with it. so far my water has been crystal clear and i have been dumping about 2 cups of household bleach to it every other day. My chlorine right now is 2.4 so i added 2 cups this morning and my ph is 7.8. I am very new at this. Also i bought small pool sanitizer last year for my kiddie pool and its granular so if i want to use that instead of bleach to use it up how do i determine how much i need to put in?
    Its also by hth.

    Thank you so much!

    it just says on the bottle contains mineral crystals for a relaxing spa experience but the active ingredients are just the sodium bisultate of 91%. The inert ingredients are 9% Maybe i better not use it and just go get ph decreased made for pools?

    You can lower pH in your pool using plain old full strength muriatic acid. There is no reason to buy anything more expensive.
