An update on this:
Okay, after replacing the pump, we had a lightning storm while I was away for a couple days. It apparently fried my new pump (maybe my surge protector was already fried?) and the tank sat without a return, skimmer, or scrubber for over 2 days completely unattended. Let's just say I came home to utter chaos and rage. All my sps were dead, one of my resident clownfishes had disappeared, and everything looked awful. This was about 2 weeks ago--it has taken me this long to even bother typing about it, because I was so angry. The only things left are my old-timers, like the half-alive bubble coral, red open brain, my oldest female clownfish, and my oargrass that I thought had completely died off (quite the opposite). I've since broken the tank down and started a 25 gallon cube as of today. I haven't gotten the lighting or overflow for it yet, though. I've been looking at one of the 250w Oceanlights, since they are reasonably cheap and about $5 more than the 150w version. That will give me lots of light for what is essentially going to be a seagrass/macro/anemone tank. I haven't really decided on what species the anemone will be, but I don't mind devoting the entirety of the tank to it at this point. It will still have many of the same bells and whistles. I'll still have 3200 gph of turnover (a big downgrade for me), 250w 10K XM, a turf scrubber for filtration, 100% kalkwasser for auto-topoff, and some carbon floating passively. I'm going to have to build a sump, though, since the dimensions of the stand are quite odd. I think I'll make a new thread in the next couple of days to chronicle this a bit. Kind of a new direction for me, since I'm fed up with higher end corals for the moment. I'm keeping the 40 breeder for any future plans that might pop up, though.
