HELP!! My pool is a mess from overuse of chlorine tabs and not using liquid chlorine. I have lowered the CYA (from 100!!) level by filling/lowering the water level several times and I have had my SWG repaired. My question is, can I SLAM the pool and use the swg to keep my FC up (by the CYA tables, I need to keep it 20ppm for now) or should I turn off the swg and keep adding chlorine until the pool is clear? Also, while SLAMMING, should I leave the filter in the "filter" or "re-circulate" mode? Thanks. Your advice has never let me down and I appreciate you all!
