I have both an undergravel filter AND a biowheel HOB on my new 55 gal tank. I figure having both will be good for redundancy in case the UGF is inadequate by itself.
I've heard of people hooking up the intake of a biowheel to the riser on a UGF in order to assist with the water flow through the gravel. Is that a good idea or a bad one?
