I think your will be just fine.Question...the FC is sitting at 16 right now. I've added 8oz to bring it up to 17. I'm heading out of town this afternoon, and will be back sometime late Wednesday or mid-day Thursday. Given the pool temp, cool weather, and current chlorine level, do you think I'm ok to leave the water alone for a few days? I suppose I could have my wife or kids add some chlorine if need be.
