API Ammonia Test Kit – Freshwater and Saltwater Aquarium Water Testing

Protect your fish from one of the most dangerous aquarium water contaminants with the API Ammonia Test Kit. Designed for both freshwater and saltwater aquariums, this easy-to-use liquid test kit accurately measures ammonia (NH₃/NH₄⁺) levels.

Ammonia is highly toxic and can quickly build up from fish waste, uneaten food, decaying organic matter, or an immature biological filter. Even low levels can cause stress, gill damage, illness, and fish loss. Regular ammonia testing is essential for maintaining a healthy aquarium and monitoring the nitrogen cycle.

With enough solution for up to 130 tests, the API Ammonia Test Kit provides reliable results and excellent value for both beginner and experienced fish keepers. Monitoring ammonia levels helps aquarists detect toxic water conditions and monitor new tank cycling progress, as well as detecting filtration issues early. The API Ammonia Test Kit is one of the most important water testing tools any aquarist can own.
