We too had a green swamp looking swimming pool We did get rid of the green but our pool is cloudy and you can see stuff floating in the pool. Small stuff that you can't get out with a skimmer. I have been working on the pool levels and it seems even when they all read good the pool is still cloudy. I haven't seen the pool bottom for about 6 weeks! Our pool does seem to be eating the chlorine and I have had to add PH up to the pool the last 4 weeks. Any suggestions?
