It instantly converts harmful ammonia into a non-toxic form, reducing stress and mortality in fish. Compatible with API Test Kits, it allows measurable ammonia control and is recommended for dosing every two days until ammonia is undetectable. Trusted for nearly 60 years, API ensures a safe, healthy aquatic environment for all fish species. ## 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.

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. ## Frequently Bought Together - API AMMO-LOCK Freshwater and Saltwater Aquarium Ammonia Detoxifier 16-Ounce Bottle - API STRESS COAT Aquarium Water Conditioner 16-Ounce Bottle - API QUICK START Freshwater and Saltwater Aquarium Nitrifying Bacteria 16-Ounce Bottle --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1780634-ammo-lock-freshwater-and-saltwater-aquarium-ammonia-detoxifier-16-ounce](https://www.desertcart.us/products/1780634-ammo-lock-freshwater-and-saltwater-aquarium-ammonia-detoxifier-16-ounce) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-26*
