If you’re an aquarium enthusiast, you already know that keeping your water parameters in check is crucial to the health of your fish. One of the most dangerous and common issues in fish tanks is ammonia buildup. Fortunately, API Ammo Lock offers a powerful and reliable solution to detoxify ammonia instantly—keeping your aquatic environment safe, clean, and healthy.
What is API Ammo Lock and Why is It Essential?
API Ammo Lock is a liquid ammonia detoxifier specially formulated for freshwater and saltwater aquariums. It neutralizes harmful ammonia on contact by converting it into a non-toxic form that is still detectable by test kits but harmless to aquatic life.
Unlike traditional methods that rely on biological filters alone, Ammo Lock provides immediate protection for fish exposed to high ammonia levels—especially useful during cycling, after water changes, or in emergency situations.
How Does API Ammo Lock Work?
The secret behind API Ammo Lock lies in its advanced chemical formulation. Once added to your aquarium, it:
- Binds and detoxifies ammonia without removing it from the water, allowing beneficial bacteria to process it naturally
- Removes chlorine and chloramine from tap water, making it safe for fish and plants
- Supports biological filtration by converting ammonia into a non-toxic form suitable for the nitrogen cycle
- Stabilizes water conditions to reduce fish stress and promote healthier living conditions
This makes it ideal for newly set-up tanks, overcrowded aquariums, or anytime there’s a spike in ammonia levels.
How to Use API Ammo Lock (Step-by-Step Guide)
Using API Ammo Lock is simple, but consistent application is key:
✅ Step 1: Test Ammonia Levels
Use an ammonia test kit (such as the API Ammonia Test Kit or Tetra EasyStrips) to measure ammonia concentration in your tank.
✅ Step 2: Add the Correct Dosage
Add 5ml of API ammo lock ammonia detoxifier per 10 gallons (38 liters) of aquarium water. Repeat every two days until ammonia is no longer detected.
✅ Step 3: Maintain Ideal Conditions
Keep water temperature below 75°F when adding Ammo Lock.
Prime water circulation for 5 minutes to help distribute the treatment evenly.
✅ Step 4: Monitor Weekly
Continue testing your water weekly. Though the ammonia may still register on test kits, it has been rendered non-toxic and safe for your fish.
When Should You Use API Ammo Lock?
- During new tank setup (nitrogen cycle startup)
- After heavy feeding or overstocking
- Post water changes with untreated tap water
- In emergency spikes of ammonia levels
- While transporting fish to reduce stress

- 🌿 Add live plants to naturally absorb excess nutrients
- 🍽️ Avoid overfeeding—only feed what fish can consume in 2–3 minutes
