I partially drained my pool back in April because of extremely high CYA levels and mustard algae issues. Once I refilled, I started using the bleach method to maintain chlorine levels and I test everything regularly with my TF100 test kit. Everything seems to be pretty perfect except for the pH. I have tested and have also had the pool store test, and we are both coming up with 7.8-8.0. I have added muriatic acid 4 or 5 times since I refilled, usually 2-4 cups at a time, and I test the next day. The pH does not budge after adding the acid and I cannot figure out why. The only 2 things that I can come up with are:
-I added PoolProof (borates) a few weeks back. This is really stumping me because, from what I understand, the PoolProof is supposed to maintain a level pH but it shouldn't be holding it at that high of a level. I was under the impression that it would help maintain the pH in the 7.2-7.6 range.
-Even though I use bleach to maintain the chlorine, I add 2 trichlor pucks to my dispenser every couple of weeks just to make sure the chlorine never goes down to 0. This is also confusing me because I thought the trichlor pucks lowered the pH.
Do you think the PoolProof or bleach/trichlor mix is causing the high pH?
Do you have any other ideas I could try to lower the pH?
My pool is 18k-20k gallons and the water looks great since doing the partial drain.
Thanks for any feedback or suggestions....... Josh
