NANFA-- Tank Filtration Question

Thu, 21 Sep 2000 12:37:20 -0500

I am hoping to someday set up a large freshwater (natives of course ) tank.
I am in the early planning stages and trying to sort out the best way to do
everything. The tank will either be a Glass 180 gallon or an Acrylic 225
Gallon. That is yet to be decided. Anyway, my question comes in the area of
filtration. I will be using an undercabinet system with an intake that
takes the water from the tank down into the cabinet, runs it through the
various canisters and then sends it back to the tank. Here is the dilemma.
The tank will be a peninsula and viewable on three sides. One short side
will be against the wall and I don't want to have tubes and overflows on
the opposite and exposed (short) end. Will the system work fine if both the
intake and output tubes are on the same end of the tank? This will, I hope,
simply create a circular water flow, but wanted to see what you "experts"
thought first. Will the water circulate properly to all areas of the tank
or will the intake simply suck in the newly filtered water from the nearby
output leaving stale water at the far end of the tank? Does it make any

Simple drawing of proposed inlet/outlet arrangement:
