Current measures:
FC/TC: 2
pH: 8.0
TA: 80
CA: 300
TDS: 1200
(Calculated LSI: 0.24)
Every week I have the same balancing issue. I go to test pool water and it has invariably drifted back up to somewhere around 8.0 (SD 0.2) (as measured by phenol red, meter occasionally reads higher but may need recalibration).I end up adding ~1.5 pints of muriatic acid and retesting the next day. The pH will have returned to a somewhat tepid 7.5 with TA remaining somewhere around 80. Of course, this constant addition eventually lowers TA and I have to acidulate the water so that it may tolerate dosages of sodium bicarbonate without becoming excessively alkaline. I had considered that the production of carbonic acid from waterfall may have been the cause, but there is no way for me to shut it of without hampering circulation.
In short: My pool consistently runs with high pH and low-normal TA. I am hoping to find some variable I’m not controlling for so I can reduce the amount of HCl introduced to the system.
Thanks in advance.
