I thought he might have ammonia for sale for doing fishless cycling!!!
J/K
If your asking how to rid your tank of it, it will dissipate in time thru the natural cycle process. If you have fish (or too many fish) in your tank you should start doing partial water changes, but this will prolong the time it takes for your tank to completely cycle.
If you have no clue as to what I just said (sometimes I don't even have a clue as to what I say) then clicvk on the links at the bottom of smb or Alien Anna's signature and they will explain the nitrogen cycle process that all new tanks go thru.
Also get some live plants, whether the plants die or not in the future (whether you want to keep them) they will help in the short term to reduce the ammonia levels
