I need to set up one of my own sometime soon, so I appreciate all the ideas in this thread.

My question: Do any of you put some form of screen in place at the bottom of the cone, or an in-line filter afterwards to keep large pieces of debris from plugging the pump, say a chunk of hard AMS or the 2" piece of foam from under the jug lid, which I have had blow off every so often and go into the tank?? I understand that this would reduce flow.
