I'm seriously considering going sump-less. I have a good volume of water in the partitioned left end of the tank. I don't plan to run a skimmer. The only reason I had planned to add a sump, was to return water to the refugium, but I realized I could just use my canister filter return instead. I like having all the water on the same level-less chance of mishaps. I've got a good closed loop setup with a Reeflow Dart. I plan no mechanical filtration at all. Since this tank is basically a large display refugium itself, I see no need.

There will be an additional refugium above the tank, so technically, the display is the sump. With no sump I won't need my coast to coast overflow, but rather than removing it, I could use it as additional refugium space. Some might ask,"why do you need a refugium if your display is already one?". The answer is "lack of predation". Hopefully, my refugium(s) can replenish plankton numbers as they are consumed in the display.

As many naturalists and environmentalists have suggested, we should set aside our arrogance,
our desire to conquer and control everything, and walk hand in hand with Mother Nature. -Walter Adey
