Thread: salt and borax addition without SWG

    salt and borax addition without SWG

    I want to add borax to about 50 ppm for the "feel" of the "softer" water. In reading in the pool school, borax raises PH - is this ongoing or just at first?

    I also want to add salt to about 2000 ppm - I have read where with SWGs some must routinely add acid to combat high PH - is this because of the salt or the SWG?

    I have also learned that the salt does not dissipate or get lost in backwashing and is lost only through splash out - is the same true of borax?

    Thank you in advance.

    Borax raises the pH at first, then acts as a buffer

    pH rises due to the SWG, not the salt

    Yes. salt, borax, and CYA are all mostly only lost through physically removing the water.

    Just to clarify, you want 50 ppm of Borates. Using Borax is one way of doing that.

    The Borax itself raises ph and you need to conteract that with Muriatic Acid addtions. Another way to add borates to the pool is Boric Acid which is almost ph neutral. Read: http://www.troublefreepool.com/so-yo...how-t4921.html

    You do lose salt to backwashing and splashout, but you do not lose it to evaporation. Same with Borates.

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.
