Marc, thanks for your thoughtful input. Actually the only problem I see is that I won't have a rimless tank in the new home, which I'll really miss. I'm actually happy to be moving into a larger tank, and like you said, there'll be enough help here that I'm not predicting many losses. But the house will not be set up in such a way that a free-standing tank will look nice; it will be better as a corner in-wall. The rimless would be 'wasted' as an in-wall tank, so I figured I might as well go larger since there is space to do so. I see your point where I've described it as a temporary QT, and I didn't really want to give that impression. I will continue to improve upon this system until the move occurs, I will acquire new corals and other inverts, probably fish as well, but this will not be my final tank. Tell you what, we won't think of it as a quarantine tank, but instead a 'grow-out' tank.
