Hi everyone! This is my first post so hope I do this right!
My pools PH rises so frequently that I am adding about 64oz muriatic acid every 2 or 3 days. After reading everything I can find on this site about rising PH, I'm guessing it might be due to aeration rather that chemistry (maybe). We use our Riverflow pump two hours a day, which causes the entire 22K pool to circulate for two hours. Also, because of many crape myrtles, high temperature (100's) and high water temp (92) I've been running the pump 24/7 at 1400 rpm, IntelliChlor at 20%. This keeps the pool sparkling at all times but I feel like I can't go away for 2 weeks because who knows how high the PH will be when I get back! So my questions are these:
Is the PH rise caused by aeration? If so, is there an automatic muriatic acid dispenser I can add to the pool system?
Would adding Borates help? I almost added them after reading those threads but thought I'd check with the experts first!
Current TF-100 test results:
FC 6.5 (high today; usually keep at 5)
PH 7.8 (might be higher; don't have a PH meter yet)
Thanks so much for your help!
