Hey all - having trouble keeping my FC up despite continuing to ramp up both my pump run time and SWG %. I'm presently running 11 hours a day at 100%, and noticed a 3ppm FC loss since yesterday (not an OCLT result, and we swam yesterday).
Anyway, my current results:
The pool is covered all night and any time during the day when it is not in use (which is most weekdays), yet I continue to struggle. I shocked to 25ppm (no, not to SLAM level for my CYA, so that also could be a problem, I guess).
At this point, should I suspect an issue with the cell? I have not cleaned it this year...
Any input would be appreciated. Thanks!
