I had a minor algae bloom. The green went away and i can see my feet in the bottom (4 feet deep). but the water doesn't easily go crystal clear. I was told by someone that when adding chlorine too much will tend to make the water cloudy. When the chlorine gets to a low level it will be clear an you have to "walk the line" of adding small amounts of CL to be beneficial but not too much to make it cloudy?
