API Ammo Lock Ammonia Detoxifier for Aquariums 16 oz (Treats 946 Gallons)

API Ammo Lock works instantly to detoxify ammonia produced by fish waste, and remove chlorine and chloramine from tap water, while eliminating ammonia stress and protecting healthy gill function.

Ammo Lock does not remove ammonia, it simply converts it to a non-toxic form. The neutral solution will not change water pH. The biological filter will then consume the non-toxic ammonia, converting it to nitrite then to nitrate. Each bottle treats 240 gallons of fresh or salt water.


4 oz treats 236 gallons

8 oz treats 474 gallons

16 oz treats 946 gallons
