Tetra Test NH3/NH4+ offers you precise and reliable measures of the overall ammonia levels in your fresh water aquarium.

Ammonia within an aquarium environment is unavoidable as it is a byproduct of the decomposition of fish waste and uneaten food. However, ammonia levels in excess of 0.25mg/l cause long-term damage to fish so it is essential that you ensure your aquarium water is kept below this.

The manufacturers recommend that you test your aquarium water on a weekly basis.
