Very nice you have pictures of your sump setup?

2 220 shipped its pretty expensive compared to my 150 shipped and they have the same 2400gph. I literally have like 4-5 of these just sitting around from old pond use and what not.
I know for a fact the one I posted is reliable and used frequently in the pond scene.
I want to see your setup because my sump wouldn't even house that pump. Mine fits perfectly but this seems more wide. I have an acrylic sump made for a reef setup but same thing for a freshwater tank.
There is an outer cage in those pumps you can remove to fit in a sump
