API Ammonia NH3/NH4 Test Strips, 25 count

The Early Warning System Your Fish Need

Ammonia is the #1 killer of tropical fish. Produced by fish waste and uneaten food, it is invisible, odorless, and highly toxic. API Ammonia Test Strips are designed to give you a highly accurate reading of both ammonia ($NH_3$) and ammonium ($NH_4^+$) levels in just 60 seconds. Regular testing is the only way to ensure your aquarium remains a safe environment for your aquatic life.

Why Every Aquarist Needs Ammonia Strips:

• Identify the "Silent Killer": Even low levels of ammonia can cause gill damage, stress, and death. These strips help you catch spikes before they become fatal.

• Instant Results: No more waiting for liquid drops to react. Simply dip a strip and read the results immediately against the color-coded chart.

• Freshwater & Saltwater Safe: Calibrated for high accuracy in all types of home aquariums and ponds.

• Perfect for New Tanks: A must-have during the "cycling" phase of a new aquarium to monitor when it is safe to add fish.

• Stay-Dry Bottle: Features a moisture-absorbing cap to keep your strips fresh and accurate for longer.

How to Test for Success:

1. Dip a strip directly into the aquarium water.

2. Remove and hold horizontally for 60 seconds (do not shake off excess water).

3. Compare the pad color to the chart on the bottle. If any ammonia is detected, immediate action (like a water change or adding API Ammo-Lock) is recommended.
