Our pool is light teal and we have put every chemical known to man in it and it will not clear up. All the levels in the pool are where they should be. The chlorine is high b/c we have put so much in (recommended from the pool store). If you put something in the water you can tell the water is clear until you get a little more that 1/2 way down and that is where the water is colored. The liner is not stained and the fitler seems to be working just fine. (the pool was a much darker green when we started this proccess) It cleared up tremeandously but is stuck at this light teal color where it has been for weeks. Any thoughts?
