## Overview

API AMMO-LOCK is a 237 ml liquid treatment that instantly detoxifies ammonia, chlorine, and chloramines in both freshwater and saltwater aquariums. It converts toxic ammonia into a safe form, reducing fish stress and promoting healthy gill function. Designed for bi-daily dosing until ammonia is eliminated by your biological filter, this trusted formula has been a professional choice for over 50 years, ensuring a safe, vibrant aquatic environment.

## Description

Product Description Fish continually release ammonia into the aquarium through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia to the water. Even small amounts of ammonia stress fish; large amounts of ammonia will kill fish. Ammonia is the #1 killer of freshwater fish. 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 Freshwater and Saltwater 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. For best results, use as directed on the product label. If your aquarium tests positive for ammonia, do a partial water change, then neutralize the ammonia with API AMMO-LOCK Ammonia Detoxifier Aquarium Treatment. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium. API Aquarium Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your tank. Make sure to use all products as directed in order to ensure the best results.

Review: ⭐️⭐️⭐️⭐️⭐️ A Must-Have for Every Aquarium Owner! - API AMMO-LOCK is an absolute lifesaver! It instantly neutralises harmful ammonia, keeping my fish safe and stress-free. I’ve used it in both freshwater and marine tanks, and it works perfectly every time. The 473 ml bottle lasts a long time, and the dosage instructions are clear and easy to follow. I really notice the difference in water clarity and fish behaviour after using it — especially during filter maintenance or new tank cycles. It’s one of those products I always keep on hand. Reliable, effective, and excellent quality — highly recommend for any aquarium setup! 🐠💧

### ⭐⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️⭐️ A Must-Have for Every Aquarium Owner!

### ⭐⭐⭐⭐⭐ Good quality
*by S***A on 27 July 2025*

Works well

### ⭐⭐⭐⭐ Works as intended but not concentrated so dosnt last very long
*by M***N on 28 May 2020*

Bought to deal with an ammonia spike. Works as intended and converts the ammonia to its non toxic form for 48hrs. Easy to use and measure out. It’s worth noting that if you are using the API ammonia test, the non toxic form of ammonia still shows up as the test looks for both NH3 & NH4. So you could be fooled into thinking this product isn’t working. I used a Seachem Ammonia Alert (which only tests for the toxic form NH3) to keep an eye on when this product was wearing off. Only issue is the bottle dosnt last very long, as it’s not a concentrated solution so if you have a prolonged ammonia issue as I did (my cycle crashed after medication) you will run out.
