    Borax vs Boric acid

    I have found a supplier that supplies borax and boric acid in bulk and very cheap.

    They are the same price for a 25kg bag.

    Boric acid seems to me superior to borax....

    Am I right?

    Re: Borax vs Boric acid

    the advantage of using boric acid rather than borax would be not having to counter-balance it with muriatic acid addition (due to pH), as well as taking less product to achieve your desired borate level.

    Yeap Boric acid is a bit easier to use.

    Why would you need to counter-balance? Aren't you adding borax specifically to up the pH? I've been using the BBB but to this point I have only had to use bleach. My pH dropped a bit recently though so I am about to add borax to up it per the pool calculator. Am I missing another variable?

    Re: Borax vs Boric acid

    I got my boric acid here:
    http://www.dudadiesel.com/search.php?query=boric

    Any of them will work, just get the cheapest for the volume you need. I used the granular, and it still dissolved very fast.

    For a pool the size of mine, it was MUCH easier.

    I tried the Borax route, this got me halfway there.

    Re: Borax vs Boric acid

    Sorry no-mas - I am in Melbourne Australia so a bit too far from FL!!!

    But just so that you know it is $50 for 25kg which is basically in your money, $50 for 110 pounds, I think.

    Not sure if that is cheap or not but we don't have 20 mule over here and don't really have big stores that sell bulk over here either....

    I also like the idea of buying a 110 pound sack of the stuff and being done with it.

    I think 110 pounds of boric acid should last a long time?

    Re: Borax vs Boric acid

    Juzzie, it will take a little over 22 lbs of boric acid to bring your pool borate level to 30ppm, so yes, I think 110 lb will last quite a while

    I plan to add borates to our pool next year. If I can find a decent deal like yours, I will certianly go the boric acid route as well.

    Re: Borax vs Boric acid

    Oops just realised I think 25 kgs is 55 lb.

    Must remember not to do maths when drinking beer. Especially when posting results up on forums!

    ??? When I used Pool Calculator and put 0 ppm in current and 30 in the goal and set the volume to 15800 I got over 24lbs. It's a small difference but I am curious how you calculated the 22lbs above.

    Use 15850 gallons in The Pool Calculator and put in 0 for Now and 30 for Target in the Borate section and select "boric acid" and I get 363 ounces by weight which is 22.7 pounds.

    Re: Borax vs Boric acid

    If the OP is using borax to raise pH, it must be borax. Boric acid doesn't do that. If you are looking for a bit of algaecide protection, better water feel and pH buffering, either will do, but borax will require lots of acid to rebalance the pH, whereas boric acid won't affect the pH.

    Borax raises pH. Hence the need for MA to bring it back down after adding borates.

    DOH! I see what I did. I was looking in the wrong blank. The one I looked at was VOLUME not WEIGHT! Ounces can be a confusing measurement for that very reason.
