## Overview

API AMMO-LOCK is a 16-ounce aquarium treatment that instantly converts toxic ammonia into a safe, non-toxic form for both freshwater and saltwater tanks.

Trusted for nearly six decades, this product safeguards your aquatic life by neutralizing ammonia stress, ensuring a healthier, vibrant aquarium environment.

## 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. 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 show a reduction in ammonia on API Test Kits, but a 25% water change is still recommended after dosing. 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 almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

## Questions & Answers

**Q: is it safe for little turtles?**
A: I am applying that API Ammo Lock on fish tank. I am not sure if it is safe for little turtles.

**Q: Since this only detoxifies ammonia, is there a chemical additive that removes ammonia? and not a filtering device.**
A: Chlorine but of course you will kill your fish, I actually tryed this product but in my experience did more bad than good. If you really want to remove ammonia in a safe way you will need to do water change daily first day 50% after that 20% for at least 5 day and then check your water parameters. Don't add more fish until your filter is cycled.Of course if your filter was never cycled you will have to continue doing water changes every other day 10-20%.  Good luck and take care.

**Q: Is this safe for an axolotl?**
A: killed my fish

**Q: Is Ammo lock usable in a tank with shrimp and snails?**
A: Yes, this product is safe for shrimp and snails provided you follow the label directions carefully. It detoxifies ammonia quickly and also removes/detoxifies chlorine and other harmful contaminants from tap water.  Yes. I highly recommend this product especially for crowded tanks. It's been a real lifesaver for my 30 gallon densely populated Cichlid aquarium.

### ⭐⭐⭐⭐⭐ Works quickly
*by T***E on January 21, 2023*

I have a 2 gallon tank with a Betta and snail. Some plants and a strong enough filter. I don’t think I over feed and clean up leftovers before turning the filter back on. I removed any dead or rotting plant pieces and did a partial water change. I used non chlorinated tap water. The next day the ammonia levels on detector were worse. I swapped out a little bit more water and expected a change. Nothing! I ordered this product it came next day. I was so concerned because directions are for a ratio of a ten gallon tank. My brain does not work well first thing in the morning and I was not going to start mixing up 10 gallons of water either. If you’re in the same boat, fear not. I’ve got you covered. I have included in pictures that the cap has measurements for 1,5 and 10 milliliters. 1ml. of solution per 2 gallons of water, 5ml. Solution per 10 gallons of water and 10ml. Solution per 20 gallons of water. Basically whatever gallons your tank is, divide in half and that number is the amount of ml. needed. Ammonia levels were reduced in minutes.
