    Bleach weak in Dallas

    I've been buying the 3 jug boxes of Clorox at my local COSTCO off Rt 75 in Plano and it's taken me awhile to determine the sodium hypochlorite is only around 2-3%, not 6%.
    I did the overnight algae test to make sure that wasn't my problem. I've been following the recommendations to get my Cl to 6.0 and it's been taking 2-3 times the amount of clorox to get it there.
    I called Clorox and they are sending me a coupon for 3 free jugs, I guess that is better than nothing. I'm going to talk with the folks at COSTCO today to see if I can get more for free, but at a later date.
    The black printing off the jug is A510018TX-109:34R. Clorox said it was made in January so it's not a shelf life issue. They also said if it froze it would get weaker. Just a heads up to anyone who might be experiencing the same problem. I'm guessing with the cold weather we've had here in Texas since January that a tractor trailor of it must have froze.
    I'm going to buy some today from Sam's to see if I get better results.

    I am in Fort Worth and get my Bleach from Costco and my bottle says 6% and using the Pool Calc app on my iPhone the bleach works fine bringing the numbers up.

    All my Costco Clorox has been fine as well. That's very strange. At least you got a coupon for some free stuff though.

    I buy at Sam's Club on Park/Greenville in Dallas and the PPM has always risen to match the 6%. I'll bet they go through a pallet every day. Very fresh.

    FWIW, I buy at the same Costco as the OP, and it has always been super fresh. They move a LOT of bleach.

    Seems like this was an isolated case (well, actually a couple of cases) which is good news. I bought some at Sam's and it worked as expected.
