First off great site ...I have been trying to read alot. I just finished filling my "new" pool Its about 15000 gallons. I had the Stonescapes pebble installed my Ph is around 8 and TA is at 50 no chlorine added yet. Whats the best way for me to bring the Ph down and TA up?? I tried the pool calulator. Just didnt make sense..(update..makes sense now was putting the numbers in the wrong fields) ... I need to play with it but for now I need a quick answer. Thanks for reading.
