Water with a pH value lower than 6.5 may have a higher concentration of lead or copper due to degrading pipes and fixtures. Water with a value higher than 8.5 typically has a higher amount of dissolved solids which can lead to scaling or build up in your pipes.
But this time â a couple of pool guys knew the answer: Itâs because the pH of soda ash is about 11.4. If you use soda ash to raise the TA, the pH of the water will also go up â way too much (not good). But when you use baking soda (a pH of 8.3) to raise the TA â the pH will not go over 8.3. In fact, if the pH of pool water is over 8.3 â adding baking soda will actually LOWER the pH.
