This is my second summer "trying to" maintain a pool. Finding it very frustrating as it seems that I continue to develop algae. The deep end begins to develop a greenish cast. I was reading through Pool School again this morning and I am thinking that I am probably allowing the chlorine level to drop too low. I thought that I read last season to test the water in the evening and add bleach as necessary. I have been doing this but during the day the level will drop to maybe 2 or 2.5 (recommended 3-7 with a CYA of 40). So I have to SLAM it again and the kids lose pool time...
Any advice or thoughts would be greatly appreciated...
