I have a 4' long 120g tank with a single 1" corner return line that I'd like to place a RFG on. Problem is that I probably am only pushing 300 gph through the sump and back into the display (I use a pair of XF250 Gyres for my main flow). What I'm trying to accomplish is breaking up the static linear flow I currently have from the return pipe and add a bit more turbulence to the other half of the tank opposite the return.
On a 4' tank at that low of flow, would you recommend I use the 1" RFG or reduce down to a 3/4"?
