Yes... now it's just *fixing* it. Aiee! No problem with scrubbing and washing the 3-gallon (and Eros is soooooo much happier in the bowl, for the moment. Wow.), but the 5-gallon I think will just have to deal with a water change every day for a bit, till I get all the schmutz vacuumed out of the gravel. At least the plants are happy in that one; they kept dying in the 3, but I think that was a pH problem too. :) Soon to be better!
