I have 2 FX5s running on a 180 gallon tank viewable from 3 sides. All of the plumbing has to hang off of one end (24"). I would like to add another FX5 but am becoming limited with space to hang more plumbing and was hoping to avoid more "mess". I would like to put the return of one filter into the inlet of another. That way I could have one in and out for 2 filters. Will this work? Has this already been done? Thanks for input/ideas.
