    PH powder question??

    Why is this :::

    HTH PH Increase bottle: Sodium Carbonate
    Baking Soda : Sodium Carbonate
    Borax: Sodium Borate

    Why do they say to raise PH use Borax, to raise TA use Baking Soda?

    Shouldnt PH+ be: Sodium Borate?

    Re: PH powder question??

    ph up products are typically soda ash aka, washing soda, sodium carbonate, Na2CO3.

    Baking soda is sodium bicarbonate aka, sodium hydrogen carbonate, NaHCO3

    From Recommended Pool Chemicals:
    Raising PH

    PH can be raised in three ways: borax, soda ash, and aeration. Borax is usually the best choice. Borax raises the PH and also raises the TA level just a little. If your TA level is low soda ash will raise both the PH and TA levels. If your TA level is high, aeration is best as it will not raise the TA level at all. However, aeration is rather slow compared to the other two.

    Borax is available as 20 Mule TeamŪ Borax Natural Laundry Booster. It is sold in the laundry detergent section of most larger grocery stores and some big box stores. Borax is best added by pre-dissolving it in a bucket of water and then pouring that slowly in front of a return.

    Soda ash is available as ARM & HAMMERŪ Super Washing Soda Detergent Booster. Do not confuse this with ARM & HAMMERŪ laundry detergent! It is sold in the laundry detergent section of most larger grocery stores and some big box stores. It is also sold by pool stores under various names, including PH Increaser, PH Up, Balance Pak 200, etc. Soda ash is best added by pre-dissolving it in a bucket of water and then pouring that slowly in front of a return.

    Aeration can be provided by a SWG, spa jets, waterfall, fountain, return pointed up so it breaks the surface, air compressor, kids splashing, rain, etc. It can take some time for aeration to raise the PH. The higher your TA level, the faster aeration will work.

    We typically suggest borax to raise ph since it has less effect on TA than soda ash (ph up).

    Sodium carbonate is washing soda/soda ash. It raises pH and TA. Baking soda is sodium bicarbonate, which raises TA, and doesn't effect pH. Borax raises pH, without much effect on TA.
