how long has it been running? is it cycled? how often are the water changes? how much? are you feeding more lately? Try a larger water change daily until the levels come back to normal... I can't think of anything off the top of my head, but I'm relatively new at fish... A totally cycled tank doesn't go into a cycle unless something major is thrown off. Could the new water have killed the beneficial bacteria? Did a fish die or was something added? How old is your test kit? if it's liquid, are you making sure to wait the allotted time and to shake the bottles that need shaking? Sorry I'm no real use.

One missed water change shouldn't make that much difference...

Did you totally change / clean your filters at the same time? Maybe disturbing both took a toll on the bacteria.
Or, is your sand bed particularly deep? It could have had a pocket of eew that was disturbed into the water...

Keep up with the testing and water changes at this point. You can also do ammo-lock or some such to make the ammonia less toxic, keep in mind if you do this the ammonia will still show up on your tests.

Good luck.
