Looking at some of the links that Chris posted in http://www.reefcentral.com/forums/showthread.php?s=&threadid=1140243 I found this picture:

Just wondering if someone can give me an idea whats going on here. Is this just stands for rock work?

I'm not sure what they are, either. But they're neat looking!

No matter now many times I "rtfm"... I just don't read enough.

Similar to what I was wanting to do in my next tank, but I don't think I'll be able to talk Glass Cages into doing too much nonstandard stuff. =\

That is what I did, but not on that scale ... My closed loop is run under the sand bed, 3/4" pvc with locline outlets and a sequence pump for flow. Intake is from the back glass with screen to keep fish etc out. Mine is in a 90 gallon, so it is a miniture of what that picture was. But it works well for me.
