Happy 2013 everyone! I've been pretty busy since the holiday, and have been neglecting both the tank and this thread.
I was away for a week over christmas, and while a coworker volunteered to feed the fish a couple of times I didn't want to complicate things with adding ferts. On coming back I was surprised to find that green algae on the glass was the only problem that had developed.
I've been working on it, but you can see it's still a long way from gone. I think it will just take some time to stabilize again now that I've restarted fert dosing. The whole tank also badly needs a trim--hopefully I get around to doing it some time next week.
