I have been rolling along all summer at TA of 110 ppm and pH of 7.4-7.5 During the past week my TA has gone from 110 to 130 to 150 in a matter of about 5 days. My PH yesterday was pushing 7.8 but not quite on the colors. I knew something was wrong because when I got out my skin was itching like crazy which led me to test the water. What would cause this. I have been running pump about 12 hours per day...What temp is just shy of 80 degrees
FC between 4.5 and 7 all the time.
pH climbing from 7.4 to 7.8 over past five days
TA also climbing
