Keep your fish thriving by instantly neutralizing harmful ammonia in your aquarium water with API AMMO-LOCK Ammonia Detoxifier. Fish constantly release ammonia through waste, and decaying matter adds more, making it the number one killer of freshwater fish. This essential liquid treatment works immediately to convert toxic ammonia into a non-toxic form, protecting your fish and promoting healthy gill function in both freshwater and saltwater environments.
Key Features & BenefitsAPI AMMO-LOCK does not remove ammonia; it chemically converts it into a safe, non-toxic form that the biological filter can process. This immediate action protects fish cells and supports proper gill function, reducing stress associated with ammonia spikes.
SpecificationsIf your aquarium tests positive for ammonia, perform a partial water change first, then neutralize the remaining ammonia using API AMMO-LOCK. For ongoing maintenance or when ammonia is detected, dose freshwater and saltwater aquariums every two days until ammonia is no longer detected.
Trust API, a brand with over 50 years of experience creating innovative, research-driven aquarium solutions, to help you maintain a beautiful and healthy aquatic environment.
