Okay folks more trouble. It's been about 1 month since I properly shocked the pool and started testing the water properly. I am in fairly good balance (see number below). I am still having alot of trouble keeping my free chlorine up. I have been trying to dial in my SWG percentage to balance the loss from daytime sun.
Just to give you some background, when we moved into the house last fall, I ran the pump 8 hours/day with the SWG at about 40-60%. This maintained the FC just fine. Since the winter (and into the Spring) it has been nothing but trouble. I am running the pump for 8 hours/day and the SWG is running 90%. I still lose FC to the tune of 4 PPM a day (although that varies a tad). After finding this site and reading, I assumed it was because all the water was out of balance and CC was high (and that was certainly a factor before I shocked). However, with the water now in balance I am stumped as to the cause. Is is bad cell?? ...
Well, I took the SWG to the Pool store, they said it tested fine. I checked the voltage/amperage on both polarities - looks good (as far as I can tell). BTW - I have Hayward/Goldline Turbo Cell (T15)
Here are the numbers if curious.
FC 1.0 ppm
CC 0.0 ppm
Incidentally, last Fall when the SWG was at 40% the pH, CYA, CH and TA were all in the same range.
Any ideas? Help!!
