I'm a pool operator for a public pool in a hotel in Las Vegas and I've been havinv problems with the pool chems lately.
The Chlorine is at 5.0
pH is 7.2
Total Alkalinity is at 150
Cyanuric acid lvl is 55
Calcium is 220
Flow rate is at 122
Pumps are on 24/7.
I hand feed everything but the Chlorine. I have 3 Rainbow chlorinators using PoolTech trichlor.
The pool is 40k gallons.
I've been just adding soda ash to get the pH up, then add Acid 5 hours later. I add the acid columnized at the deepest part of the pool. This way, it lowers the Total Alkalinity more than the pH. But it still brings the pH way down.
Has anyone had this problem before? This happens a couple of times a year where the TA is too high. It eventually goes away. Not sure what causes it. The pool doesn't get TOO busy. Maybe 40 bathers in a day recently.
