I've run into a problem with my TA. This is an older pool and the PH is fairly constantly rising, which I've been fighting with MA. The pool has some moderate to severe calcium scaling perpetrated by the previous owner, so I've been trying to keep the Ph around 7.2. In addition to going through 2 gallons of acid a month doing this, my TA has fallen from around 90 to 60 over the past few months.
This has not seemed to assist with my PH rising troubles very much, maybe slightly. Even with the Ph having crept back up to 7.7 when last measured, my CSI has gone down to -8.8 with the lower TA.
Since the water temp is going to be going up soon, does this need attention, or can I leave the TA where it is? And if anyone has any theories as to why my pool is a Ph increasing MACHINE I'd be all ears as well. Thanks!
