Having an issue with th PH in my hot tub. I recently drained and filled the tub with fresh water and Bromine salt. Initially my TA was 0, and PH was 7.3 so we added baking soda to raise the TA. TA went to 120 and the PH to 8. I added 1 oz of muratic acid which lowered PH to 7.5 for a day, now my PH is back at 7.9. Tested TA again and it's 50 PH is again 8. This cycle is recurring and and with a TA at 50 i now need to add baking soda again. Just looking for thoughts on why my PH keeps driving up so fast. I know it will gradually raise, but within 12 hours is just ridiculous.
