Ammonia at any quanity can be quite toxic.... I'd suggest a good water change and start running some activated carbon.

Then start looking for the source of the ammo...
Have you lost any fish or critters lately? A fish dying and going unoticed can produce these effects if your cleanup crew doesn't find him right away.
Any chance a lot of excess food has been added to the tank?
things like that.

Isolate the source and eliminate it and you'll be good to go.
