By saying swamp, that implies the pool is green to some extent. If you have visible algae, leave it there for sure.

I would call it more cloudy than green. When I brush the pool I can see a fine light brown mist, like dirt, which I assume is some type of algae. Does this make a difference? I'm trying to keep it at 20ppm and run 24/7.
