Sounds like you pumped some hydrogen sulfide into your tank.

Do a google search on what to do.

Here's some more help:

"I have also seen hydrogen sulfide cause sudden fish mortality. This compound, which is a byproduct of anaerobic metabolism, is extremely deadly. It can be liberated into the water when anoxic (low oxygen) areas of the gravel bed are disturbed or when a canister filter is turned off for a long period of time and then is turned back on. If the bottom materials, like crushed coral or live sand, are provided with a constant flow of oxygenated water or disturbed frequently enough, by the aquarist or by fish, then hydrogen sulfide should not be a problem. If you turn off a canister filter for a long period of time (four hours or more) it is important to take it apart and clean it before turning it back on. Airborne contaminants, such as tobacco smoke, insecticides, paint fumes, glass cleaner, furniture polish and so on, can kill fish as well."
