I saw this idea somewhere and tried it. It not only is easier maintenance than a filter sock, but it completely quited my sump! Take an empty 2 liter bottle and cut a rectanglular hole in one side large enough to get your hand in. Drill numerous small holes around the bottle. You will need enough holes to allow the water to flow out at the same rate it is coming into the bottle. I did about 6 rows of 10 holes each. Get a threaded pvc connector that will screw into the top (the guy at Lowe's found mine in the hose fittings section). Get a connector that will fit into your downpipe that empties into your sump. I had to use an elbow to allow my bottle to lay sideways. Fill the bottle with filter floss (i just bought a huge bag of fiber fill from Wal-Mart). Rinse it before you put it in the bottle. Don't pack it tight as the water will not flow through it quickly enough. Make sure you put the hole for refilling the fiber at the top of the bottle when you attach it So that changing the fiber is easy. I just put mine in, but my understanding is that you only have to change it every two weeks or so. As an added benefit, this has made my sump almost silent!I apologize if this idea has already been shared on here!
