I have one of the metal framed, vinyl lined pools like you purchase from Wal-Mart. It came with the vacuum that attaches to a garden hose. This works ok for some stuff. I ended up with a pretty discolored pool I used a product called Green to Blue (I think that is what is was called). It worked wonders, my water is now clear, however, there is a tremendous amount of "dirt" on the bottom of the pool. I used the vacuum that I have but the "dirt" is too fine for the bag, it just returns and clouds up the water. A friend gave me some old pool supplies, it had a hose that attaches to the skimmer and a vacuum head (I made sure there was not air in the hose). When I tried that I think I may have ruined my pump, so I attached another pump. I have very little suction from the pump and when I do get a decent amount of suction the water that returns to the pool is dirty. A couple of questions... Do I need a heavier duty pump? And more importantly, any suggestions on getting the dirt of the bottom of my pool?
