The Deo-Ban is offered by us that neutralizes ammonia and nitrites that can build up in aquarium water. The aqueous urea solution is injected in the exhaust air stream, where it evaporates into ammonia. Mixers are utilized after the injection to insure an even blend. Ammonia is the most harmful toxin to the fish and you need to get rid of it fast. It is the most common cause of death of a fish in the aquarium. The Deo-Ban is made for use in the various commercial and industrial uses. The solution is made for safe use in the different places.
