API Ammo Lock 473ml

API AMMO-LOCK Freshwater and Saltwater Aquarium Ammonia Detoxifier works instantly to detoxify ammonia, chlorine, and chloramines in fresh and saltwater aquariums. It protects fish cells and promotes healthy gill function by eliminating fish stress caused by ammonia. API AMMO-LOCK Ammonia Detoxifier Aquarium Treatment does not remove ammonia from water; it converts it to a non-toxic form. Aquarium water will still test positive for ammonia until it is removed by the biological filter.
