    Chemicals
    Bleach (for chlorine)
    Borax to raise pH directly
    Muriatic Acid=Dry Acid to lower pH
    Both will lower pH but they are not the same...Muriatic acid (hydrochloric acid) is less expensive, dry acid (sodium bisulfate--creates sulfuric acid when dissolved --oversimplified explanation) is easier to handle but it does put sulfates into the water.
    Baking Soda=Sodium Bicarbonate=Total Alkalinity Raiser (to raise Total Alkalinity - will also raise PH a bit)
    Soda Ash=sodium carbonate='washing soda'=sal soda' raises both pH and Total Alk equally
    CYA/Stabilizer/Conditioner to establish the correct CYA level
    Polyquat 60%--the ONLY algaecide you should use, on occasion
    You got the chemistry down!

    By the way....I got a D+ in Chemistry class in highschool!
    This is probably the most I ever understood the whole subjuect!

    I guess now I have an incentive to understand it.....reduce pool costs! :-)

    thank you all!
