Unlike baking soda, which is also a buffer, once you add borax to a pool, it stays there. (The baking soda tends not to, or else to build up to excessive levels, for complicated reasons.) However, when you first add it, it will raise the pH a lot. For this reason, it's also superior chemical for raising pool pH. Use it instead of pH UP (sodium carbonate, soda ash). If you are having problems with your pool akalinity being too high, you should always use borax instead of convential pH increaser.
