Ammonia,one of the worst killer of fish in your aquarium, so if you are doing water changes or if your water suddenly has an ammonia spike, immediately treat it with API AMMO LOCK. API® Ammo Lock is scientifically proven to protect fish against harmful ammonia by converting poisonous ammonia into a non-toxic form.  Ammo Lock works immediately, in both freshwater and saltwater aquariums by detoxifying ammonia and removing chlorine and chloramines.  Ammo Lock does not remove the ammonia but locks it up as a nontoxic form until it can be filtered out through natural biological filtration (detoxifying).

Ammo Lock works instantly in both fresh and saltwater aquariums, eliminating fish stress caused by elevated ammonia levels and promoting healthy gill function.
Note that if your aquarium tests positive for ammonia, it is necessary to perform a partial water change first, and then neutralize the ammonia.
