You shouldn't really nead ammonia remover unless you've had a crash and its a last resort. A properly established aquarium will convert the ammonia to nitrite, and then the nitrite to nitrate. How heavily stocked or new is your tank? etc.
Personally, Filter floss/sponges, and depending on the tank mates and whats happened (Meds, water quality, PH, etc) , Carbon or Peat moss.
