Welcome to our forum.
PH is around 8.0, TA is around 80. From past experience, I think that if I can get the TA up to 120-140 the PH will stabilize. in the 7.6 range. I recall a post sometime back about a proceedure where you would shut everything off and let the water get totally dead calm and then dump a good dose of baking soda in the middle and let it sit for 30 minutes or so. This would raise the TA without affecting PH much. Can anyone help me out with this?txwillie
I may be wrong, but I dont think that having the water calm vs agitated will make a bit of difference. pH is going to change if you add any thing acidic (H+) or basic (HCO-)...
I may be wrong, but I dont think that having the water calm vs agitated will make a bit of difference. pH is going to change if you add any thing acidic (H+) or basic (HCO-). So adding sodium bicarb has to have some effect on pH, but since it itself has a pH of 8.3 (thanks, Doc) it cannot change your pH by more than 0.3. When I have been in that situation, I add baking soda as needed to get the TA in a good range, and then a bit of acid (or if it is time to shock, it is a convenient time for MPS) to drop the pH. I know that others handle it differently, but I can't keep a happy tub if the TA is only 80.
