TheProdibio Stop Ammois a natural ammonia neutralizer that instantly locks toxic ammonia into a harmless form and helps reduce nitrite, protecting fish in any freshwater or saltwater aquarium.

Browse the rest of our water care and conditioners to keep your water stable.

Ammonia emergency, handled.Stop Ammo traps free ammonia within minutes so it cannot burn gills, then keeps working to reduce nitrite as your biofilter catches up. Each dose comes in a sealed glass ampoule for full potency and a long shelf life.

How It Works

Ammonia is the most dangerous toxin in aquarium water, and it climbs fast in new tanks, overstocked tanks, and shipping bags.Stop Ammouses plant extracts that have a natural ability to capture ammonia nitrogen and convert it into a stable, non-toxic, non-volatile form, then on into harmless compounds. That removes the immediate threat to your fish and also lowers the nitrite that ammonia would otherwise feed. It works in both freshwater and seawater and is safe to use alongside live bacteria products like BioDigest.
