    Household bleach vs store bought liquid chlorine

    Still haven't figured out why bleach and not liquid chlorine. I can buy 121 ounces of 8.25 bleach at Walmart for $2.94 but I can buy 128 ounces of 10% liquid chlorine at the pool store for $2.47. Can someone explain

    Welcome to TFP!

    Nothing wrong at all using liquid chlorine vs. "household" bleach. They contain the same active ingredient, just at different strengths. The higher concentrations will lose strength quicker than lower concentrations which is why product turnover is important. The pool store likely has a much better turnover on this product than a "Big Box" home improvement store, so you are probably fine purchasing it at the pool store. As a test, dose the liquid chlorine according to what PoolMath tells you for the % concentration of liquid chlorine you are using. After about an hour, retest FC. If the FC is at the target you expected after the addition, you're fine. If not, then the liquid chlorine has lost some of its strength.

    Plus, to add to what Bo said - many areas of the country do not have "store bought liquid chlorine" available. Sun belt states Florida, Texas, Arizona and the like it is sold on every corner. I would have to drive hours to find any.

    Your case is not quite typical I dont think.
    We recommened bleach simply because it is usually a little cheaper and easier to come by than the more potent liquid chlorine.
    the active ingredient of Sodium Hypochlorite is exactly the same between the two.

    That is an excellent price on the LC, go for it!

    Thanks for the help and I do live in Arizona. i have 3 pool stores within a mile of me. Sounds like liquid chlorine is my way to go. I will do the math and see how it works out though.

    I'll bet the pool store stuff in the returnable bottles will be the way to go.
