I've got an overflow that feeds into a rectangular 2 qt container I placed in the refugium. Its about 2" x 8" x12". I cut a slot in the container about mid height to allow bubble free water to flow into the rest of the tank. I also have a HOB skimmer that pulls from the tank and feeds into the container. From there, any bubbles rise and the bubble free water goes through the slot to the rest of the tank.

I have a small pump (only about 200 gal/hour) that pumps back to the display tank. The pump has suction cups, so I mounted it on the side of the tank close to the water surface. This way if I lost siphon in my overflow, the pump would run out of water before it overflowed the DT. I used an old Ehiem return nozzle and drilled siphon break holes to minimize drainage in case of power outage. After simulating loss of pump, I've marked the fill line.

It's not the prettiest sump, but I've ran it through the tests and I think I'm flood safe :-) I'll post some pictures on my reef chronical page tomorrow.

I put the sand in last night. I think I'll probably add a light eventually, but I figured for now I can at least get the bacteria colonies going. What do yo think?

I read about "Cheato", it sounds interesting. If I were to use this, would I need to keep the lights on 24/7 to avoid having it go "sexual"? From what I've read, it sounds like I wouldn't need much light for the 10 gal... Would 10 to 20 watts be enough?

Thanks!
