Has anyone ever seen a canister/under gravel filter hybrid? I was wondering why no one has built one. Or a sump/reverse under gravel filter for that matter. Any ideas?
To be more clear, instead of having your canister sucking water through a sponge in the corner, why not have your canister sucking from a perforated platform underneath the gravel?
Similarly why not have your sump return to a platform underneath the gravel? I'm told reverse UGF's are actually better than standard UGF's.
Wouldn't either of these methods be a form of "free filtration"?
Just an idea. Any thoughts?
