The weekest link in my system up until now has been my piddly little refugium / joke of a frag tank. Well, no longer. I picked up an old hagen tank from the basement of the LFS and fixed it up. I took the top trim off and added glass bracing instead, then I drilled it to house a 1.5" bulk head. It's 30x12x15" and fits quite nice in the cabinet right beside my sump.
Holy crap there were some serious micro bubbles floating through this tank. Solution: I have an old overflow box with built in baffles. I hung it on the inside back of the tank and ran the drain into it. The results were about 90% lesss bubble, which is tolerable for a frag tank.
I still might mess around with the frag rack a bit to create more room for the abundance of frags I plan on making soon. I just hope that the 4 T5's I have over the tank will be enough to sustain my SPS frags.
