As I mentioned before I don't have a very good test kit so I took my water to the pool store. The guy who tested it said my FC was 2.0 and Combined Chlorine was 2.0 so he said that would make my Total Chlorine 0. Is that correct? I didn't take the water sample near any return and the pump wasn't on. I'm going to test my chlorine again in the AM to see what it reads.
