I was tired of the frequent rattles in the old eclipse hood over my 20 gallon long so I removed the pump and rigged up a spare Eheim 2013 canister outflow to spill into the filter box. This way I can still get the benefit of the spinning biowheel, and I get some added filtration with some floss laid in there. I just have sponges and bioballs in Eheim so I should not have to service it very often. The 2013 does not produce as much flow as the original pump but it still spins the biowheel. I like the mellower (and quieter) result. ![aug 12 2013 012.JPG aug 12 2013 012.JPG](https://www.aquariacentral.com/forums/data/attachments/165/165897-dcacc06a56b3d08e196a94f1bb392bcb.jpg)
