I recently put up a 10472 gallon saltwater generator pool. I didnt run the generator long enough to make enough chlorine, so of course I had green water... Since then, with alot of back washing, adding more salt, and running my generator longer and my sand filter 24/7, the green has changed to almost clear. The problem now is low chlorine readings and high ph readings. I just bought new test strips and will go home and test again. I guess ill know with these new strips where I stand.
