For the last month I have been struggling to maintain a free chlorine level of 2.0 in my pool. I've maintained my PH (+,-)7.5, CA (+,-)60, TA(+,-) 100, Salt(+,-)3400. I've increased my run time from 8 hrs/day to 12 hrs/day. I've also increased the SWG's sanitizing output level to 60% and recently up to 80%, resulting in little or no change to my free chlorine level.
I have just completed a "Boost" mode, running my sanitizer at 100% for the last 24 hours. My chlorine level is: FC= 1.4 & CC= 1.0.
Is it possible that my SWG is defected? I'm really at a lost as to where to turn from here.
It's entirely possible that your new cell is defective and has failed prematurely. Do you have somewhere you can take it to be tested? I would think it's still under warranty.
