We had our pool installed last year which included the Pentair Intelliflo Variable Speed Pump, large DE Filter, and the Pentair 320. It seems like I'm never able to get a lot of chlorine from the chlorinator even when it is turned on the highest setting. I'm considering switching the feeding tube to the top hole but wanted to hear if anyone else has had the same problem. I tend to run my pump at abour 2250 RPM and getting around 12-15 psi at the filter gauge. We have a 23k gallon pool and I'm running pump about 8 hours a day. Seems like the chlorinator is going through about 1 3 inch tablet a week which doesn't seem like much when turned to the highest setting.
Any help is greatly appreciated.
