Ching:
I have admired your tank from the beginning. It is truly one of the world's great private reef tanks.
I am interested in your drains. I would like to drain my tank into a separate room on the same level as the display and would run the drain and return pipes under the floor as you have. Have you calculated how many gallons per hour each two inch drain pipe handles? (I know it is a function of the length of the horizontal runs and the number and size of fittings, but I have no idea how to calculate it). I'm sure you have left some head room above the capacity of the return pump -- how many gallons per hour is it pushing back to the tank?
Also, do you have any issues with air being trapped in the pipe? If so, how do you remove it. Finally, are the drains creating a siphon or are they open?
Thanks in advance.

Art. Sorry for late reply.
I didn't calculate for the drain pipe. You don't have to worry about that because the high pressure from the drain pipe to the sump.
And my return pump is adjustable so I can control the water level.
I don't have issue with air being trapped in the pipe.
The drains are open.
