- How in the heck is it that people can manage to get fish to the point of
- spawing and then kill the biofilter on them?!? Do you have the vaguest
- clue what you have done? A massive bacterial die off is now in progress
- in your tank; If it doesn't kill the adult fish you may consider yourself
- lucky. Not only is the biofilter not filtering, it is now contributing
- large amounts of dead nitrogenous waste to your tank.
-
- For now: remove the dying gravel. Ideally, move the fish into a tank with
- a functioning biofilter. If none, change water. Put in a couple of sponge
- filters. Pray. Change water. Pray. Repeat. You have just set your filtration
- back to that of a new, unconditioned tank. You might just as well pull the
- UG plates while you are stripping the gravel out. A bare tank with sponge
- filters is a pretty good spawing envronment for many fish. Some prefer
- a rock, such as a piece of slate, to spawn on. Had you not killed your UGF,
- you could have put a piece of slate above the gravel and avoided this whole
- mess.
