I'm glad I found this group. I live in West Virginia. My wife and I bought a new house with an AG pool. It was clear when we looked at the house and when we moved in it was dark green. We spent 1.5 weeks with one pool company and went to another pool company 1.5 weeks ago. In that three weeks the pool is still green. I am hoping you all can help us. I am going to order a test kit and will ask questions when I have some numbers. In the mean time I have been doing a lot of reading around the forum. Thanks for being hear and for any help I get.
