hello, so i have a fluval evo but would like to upgrade. im looking into a fijicube rimless overflow that is predrilled and ive been toying with the idea of using the evo as a sump for this, im not an expert and would like some help with a design, so im thinking of and another divider in the center of the display area and use the AIO portion as a "in sump, sump" for added filtration by keeping all of the stock chamber components, using the middle main section as a refugium, but im not sure as to how i would effectively plumb this up to the main display, any advice would be great ill try to come up with a mach up on paint or something.
