cool, thanks, guys, that gives me some things to try. I have left the lights off and no feeding for 2 or 3 days before. I have some plants that I'm trying to sell but can't get rid of that I might try in there, but they'll probably be disrupted and not get enough light. I'll try the UV if that and more oxygenation don't work. I may get a sponge filter to stick on the AC110 powerhead, too.
I'm actually building a sump for it, too. I'll need one anyway when I upgrade.
