i would leave the refuge the height like 10.5 and the the baffles have like 3 under over and under keep them around 8" y9ou want ot have somewhat a drain off too like you stated.

However its going to depend on how much water drains off after the pumps shuts down. you can always have a small hole drilled into the return line. Just above the water line so the siphon breaks the water there.

The drain in my tank has a little whole at the top with a plastic tube sticking out of it. So I don't think there will be much water draining down as soon as the power goes off. I guess I'll have to check the depth of the drain and the water level I'll keep to calculate the amount of water that might drain down.

Mike was referring to a hole in the return line to prevent backsiphoning of the DT
The siphon will break wherever you drill the hole, instead of it siphoning to the bottom of your return outlet
If you go this route, keep in mind that the drilled hole will be spraying water while your return pump is on, so plan where you want it pointing

Oh I see. My return line also has a hole on top of it.

And I had no idea about the hole spraying water while the pump is on... I'll have to take a look into it. I think I'll clean my tank today and take a few pics and show you guys what my tank's return line and drain pipe looks like!
