Aquarium Water Detoxifier, 4 oz

Ammo-Lock® will remove the two chemicals most commonly used to treat municipal water supplies-chlorine and chloramine-both of which are highly toxic to fish and invertebrates. Ammo-Lock® will also convert ammonia produced by fish waste to a harmless compound. Ammonia is the number one killer of tropical fish and regular detoxification will neutralize it. Four-ounce bottle treats 240 gallons of fresh or salt water.
