Prodibio Stop Ammo
The Prodibio Stop Ammo is 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. Made from a special plant extract, it is the fast, fish-safe answer to an ammonia spike, a new uncycled tank, or the stress of moving and transporting livestock. Browse the rest of our water care and conditioners to keep your water stable.
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 Ammo uses 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.
