I wasn't very good about water changes until about a month ago. Before that, I did 50-75% water changes every 6 weeks or so. Here's what I have on record for maintenance though...

9/20/09- 50% water changed, gravel vacuumed
11/12/09- 30% water changed, filter foam replaced
11/19/09- 30% water changed, gravel vacuumed
11/24/09- 30% water changed
12/3/09- 30% water changed, gravel vacuumed, filter foam rinsed
12/11/09- 30% water changed
12/15/09- ammo chips added
12/16/09- 15% water changed, gravel vacuumed

hmm....6 weeks is a long time to go without water changes with that stock - leading to old tank syndrome.

sounds like your problem will go away with regular 1/3d weekly water changes.
