If you've only got a week, I'd just limp em through- you're going to lose weight, but it shouldn't slow down maturity.

Seriously, have a look @ the ario aerators- they seem pricey until something like this happens.

Bleach the living sh*t out of everything ( water pumps, airstones,tubing, etc) between runs. Rinse a couple of times and let air dry.

Run a little subculture/voodoo juice/ other innoculant when you fire back up- yer system is clearly good at raising bacteria, so try to make sure that yer raising friendlies.

Don't kick yourself, guy- yer learning about the problems of being overly sucessful. Lotta folks would like to have your problems. Ya just overshot a little.

Get me stoned sometime and I'll show you how to build an aeration tower
