Just Thought I would introduce myself first!! I live just outside Tampa, FL. I had been going to a local pool store for my advise for a while, Well recently they went out of business. So I figured I would goto Pinch-A-Penny to get my water tested, well I don't think they know to much of what they are talking about. But I took there advise anyways, figuring they're in business for some reason. Well my pool got worse then it was... Thanks. The problem I have is my pool is not screened an partly shaded by a huge oak tree which in the fall dumps tons of leaves an pollen into it. So I figured I would turn to people that know what they are talking about.. I'm going to go get my water tested again today and will post a new thread with results an pics!!
