    Borax losing it's moisture?

    Finding cheap borax (cheap anything!) in Australia is not easy.

    For starters, cheap Borax is not available here in supermarkets or hardware stores. We can get Borax... but the price for the same weight as a 76oz box of 20 Mule Team, in Australia is $18 per box!

    HOWEVER I have found an ebay seller that is selling 25kg / 55lb bags of Borax for $40 (+ $35, $50 or $90 shipping for one, two and five bags respectively) which brings it back down to the only-double-the-US-price of $3 per kg(which is usually considered a bargain here!)
    What he does state is "Bags marked 25kg but have lost moisture and now weigh 22-24kg"

    I'd be really grateful if someone with knowledge of this stuff could tell me:
    Firstly is it likely to be the same Borax which I would need for a pool? (Does it have varieties?)
    And secondly does Borax have a shelf life? As it sounds like it is going to have been sitting around for a while.

    I am certainly not at the stage of putting Borates in my pool yet (I need to get it balanced first)
    But I was leaning towards "No" due to the $200 cost of enough Borax from the hardware stores!
    This could reduce that cost dramatically and make me consider it, if it's a viable solution.

    Many thanks for any help.

    I don't know the answer to your question. But, Why do you want so much borax? For pH adjustment or to add optional borates?

    It would be to add optional borates.
    I would only need 26kgs for 50ppm according to PoolMath.
    The shipping for the rest was just to add context really!

    Get your pool chemistry balanced, your water clear, and maintain your pool for one swim season without borates. Then make the decision whether or not they are needed.

    I completely intend to, I guess I got carried away looking into the future and seeing a good price!

    +1 to this. Most of us don't even use borates. They can be helpful, but certainly aren't required.

    Welcome to TFP! Glad you found us.

    Yeah I saw these as well, noticed that the same seller is also now listing 25Kg of boric acid for $50 as well... Much better deal as you don't need the muriatic acid.

    Two mustard algae events, lots of bad pool store advice - double the salt level it should be (sigh), large amounts of copper based algaecide, 50 litres of 12.5% liquid chlorine, 2 litres of clarifier. $300 in chemicals in two weeks.
