With the Tropic Marin NH4/NH3 Test Freshwater / Saltwater, you can easily and accurately test ammonium and ammonia levels in both freshwater and saltwater aquariums. This high-quality test kit has been specially developed for demanding aquarists who want to maintain optimal water quality in their aquarium and prevent problems.
Why test for ammonium and ammonia?
Ammonium (NH4 + ) and ammonia (NH3) are important indicators of aquarium health. Ammonium is formed from the breakdown of organic material such as food residues and feces. Depending on the pH value, ammonium converts into toxic ammonia, which can be dangerous for fish and invertebrates, especially at a pH above 7. Regular testing is essential, certainly when starting up a new aquarium or after adding new inhabitants.
