Jimmyhotspring Posted April 29 Report Share Posted April 29 Hi all,My city water that I use to fill my spa has a pH of 7.5 which is what I want, but TA is very low coming in at 25ppm. If I try to raise the TA where I would like it around 80ppm it will throw the pH out of wack going way high. In the past I have tried lowering the pH with bisulfate then bringing the TA up using bicarbonate. Should I not worry about low TA if my pH is in range? I was hoping someone on here has maybe gone through this and has some insight. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
