Actually I described things inaccurately in my earlier post. The MJ1200 is attached to a pvc pipe that goes down the back behind the rock, then is split and runs under the sand to the two rotating heads at the front of the tank. The green duck-bill looking spout is the return line from the fuge in back. The flow is pretty good, and the rotating heads seem to keep it random enough that most of the SPS pieces he's put in have been pretty happy. He hadn't ever done SPS before and he's lost a couple pieces, but they both bleached out, and I just think that they didn't have time to acclimate to the lights properly. He also lost a few mushrooms to the lights when he moved them from the 6gal that I've got to the new 18gal and went from 32w pc to 96w pc. He put them under the overhangs to try to shade them but they didn't make it. Overall it's been very stable and happy from day one. It took him about 2 months to get all the pieces planned and made before it actually got water in it. That kind of planning usually pays off. I really like the aquascaping in the tank. He had one good sized piece of table rock in his main reef at home, and he bought another good sized piece and he just broke them up so they'd fit, then arranged them until he liked it and epoxyed them in place.
