I noticed in the pool school that recommend FC for SWG-pool is about 4+ (CYA 70+). I was under the impression that home pools should be FC 2 to 4. I keep mine barely at FC 2 (CC typically .5 at most). If the water stays clear, is that bad? Does the pool school recommend FC 4+ for safety or water clarity?
To that affect, does FC generated by SWG disinfect, or do I need to occasionally add a stronger chlorine (typically Dichlor, when SWG gets behind)? ...or if I find a dead rodent in the pool, can the FC from SWG disinfect, or do I need to supplement with something stronger?
