We own an 18 foot (4 feet deep) round above ground pool. We live on a farm and use well water and it is very, very rusty apparently. We filled the pool over a time span of four days with the garden hose and at about the second day we noticed the rust sedimenting on the bottom. We are talking about a quarter of an inch of sediment. We bought a 1.5 HP pool pump this year to help try to keep the pool cleaner. Problem: This pump has a basket that will catch leaves, large bugs etc, NOT small bugs and definitely NOT rust. We then bought the basket socks to filter out the rust and I bought an automatic pool cleaner that attaches to the pump intake and the little guy cruises about the bottom sucking up rust...which promptly sprays (high power I must add) out the outflow. I bought pillow stuffing and packed the filter basket with it but it doesn't help much and is hard on the pump. So the water was a murky brown, rusty color....until we added chlorine and de-algae stuff. Now the water is white, like milk, can't see the bottom, and foamy! A covering of whitish rusty colored foam now covers the pool. I am fed up. I have no idea how to filter out the fine particles. HELP ME!!!!!!!! Please.....
