Does anybody have any experience adding an under-tank sump to an AIO aquarium? It looks like the options to do that would be either drilling the back return chamber, or using an HOB overflow.
It could be way more trouble than it's worth. I'm just brainstorming because I want to upgrade the return pump that came with my AIO. The limiting factor is the width of the return chamber in the back of the AIO. It's only 3.7" and the pumps I'm interested in (Cor15 and Vectra S2) are 3.8"+
Alternatively, could I just skip the sump and plum one of those pumps externally?
