API Ammo-Lock

Instantly Detoxify Ammonia and Protect Your Fish

API® AMMO LOCK ammonia detoxifier is proven to convert poisonous ammonia into a non-toxic form, providing instant protection for your fish. This fast-acting formula works instantly in both fresh and saltwater aquariums, removing ammonia, chlorine, and chloramines to create a safer environment for your aquatic life.

How It Works

AMMO LOCK works by converting toxic ammonia (NH3) into a non-toxic form that is safe for fish but can still be processed by your biological filter. This immediate detoxification gives your beneficial bacteria time to break down the ammonia naturally, preventing fish stress, gill damage, and potential death from ammonia poisoning.

Key Benefits

• Instant Action: Works immediately to detoxify ammonia on contact
• Triple Protection: Removes ammonia, chlorine, and chloramines in one treatment
• Versatile Use: Safe for both freshwater and saltwater aquariums and ponds
• Detectable Formula: Now detectable by API Ammonia Test Kits so you can monitor treatment effectiveness
• Emergency Treatment: Essential for new tank syndrome, filter failures, or overstocking situations
• Filter-Friendly: Converts ammonia to a form that beneficial bacteria can still process

Available Sizes

Choose the right size for your aquarium or pond:

• 4 oz. - Perfect for small aquariums and emergency treatments
• 8 oz. - Ideal for medium aquariums and regular maintenance
• 16 oz. - Great for large aquariums and multiple tanks
• 1 gallon - Professional size for ponds and commercial applications

When to Use AMMO LOCK

Use AMMO LOCK whenever ammonia is detected in your aquarium or pond, during new tank setup when beneficial bacteria are still establishing, after filter maintenance or cleaning, when adding new fish, during medication treatments that may harm beneficial bacteria, or in emergency situations like power outages or filter failures.

Important Usage Note

If your aquarium tests positive for ammonia, it is necessary to perform a partial water change first (25-50%), and then neutralize the remaining ammonia with AMMO LOCK. This two-step approach removes the bulk of the ammonia while detoxifying what remains, providing the best protection for your fish.

Ideal For

Perfect for freshwater aquariums, saltwater aquariums, koi ponds, goldfish ponds, and any aquatic environment where ammonia levels need immediate attention. Essential for new aquarium setups, heavily stocked tanks, and emergency situations.

Frequently Asked Questions

Q: How quickly does AMMO LOCK work?
A: AMMO LOCK works instantly upon contact with water, immediately converting toxic ammonia into a non-toxic form.

Q: Will AMMO LOCK harm my beneficial bacteria?
A: No! AMMO LOCK is safe for beneficial bacteria. It converts ammonia to a form that your biological filter can still process, allowing your bacteria to continue their important work.

Q: Can I use this in my pond?
A: Yes! AMMO LOCK works in both aquariums and ponds, freshwater and saltwater. The 1-gallon size is particularly convenient for pond applications.

Q: Why do I need to do a water change before using AMMO LOCK?
A: A partial water change removes the bulk of the ammonia, reducing the overall toxin load. AMMO LOCK then detoxifies the remaining ammonia, providing comprehensive protection. This two-step approach is more effective than treatment alone.

Q: Will this affect my ammonia test results?
A: AMMO LOCK is now detectable by API Ammonia Test Kits, so you can monitor both total ammonia and verify that treatment has occurred. Some test kits may still show ammonia present because they detect both toxic and non-toxic forms.

Q: How often can I use AMMO LOCK?
A: Use as needed when ammonia is detected. However, AMMO LOCK is a temporary solution—you should also address the root cause of ammonia buildup, such as overfeeding, overstocking, or inadequate filtration.

Q: Is this safe for all fish species?
A: Yes, AMMO LOCK is safe for all freshwater and saltwater fish when used as directed.

Q: Does AMMO LOCK remove chlorine and chloramines too?
A: Yes! In addition to detoxifying ammonia, AMMO LOCK also removes chlorine and chloramines, making it useful for treating tap water during water changes.

Q: What's the difference between AMMO LOCK and regular water conditioner?
A: While regular water conditioners remove chlorine and chloramines, AMMO LOCK also specifically detoxifies ammonia, making it essential for emergency situations or new tank setups where ammonia is a concern.
