Well, none of the pool places in town have the type of test kit you guys are talking about. I haven't tried WalMart yet. But I did find one of the pool places that offered for us to bring in some water from the pool and they will analize it and tell us what we need to do. So I'll probably try that in the morning, if they give me the results of the test I'll post them and you guys can see what they tell me. If I can't find the test kit at walmart I'll order the one online tonight.
