I have a new pool, 12,500 gal. gunite pool with a 40 yard sandstone stream that drops 17 feet over 7 landings into the pool. Pool has been filled for about 1 month and the water is looking perfect however I have to add 1/2 gallon of Muriatic 5 times per week to keep the ph at 8 or slightly lower. Chlorine varies from 1-3. I have recently, yesterday, gotten the total alkalinity to 100 and am trying to keep it that way.
I was hoping that there is some explanation from some of you seasoned pros that might help me understand this issue and/or do I have a problem. Thanks for any advice.
