This kit uses a salicylate-based liquid reagent method to measure dissolved ammonia in aquarium water, reading across a 0 to 8 ppm range. It includes two dropper bottles of test solution, a glass test tube with a snap-tight cap, and color cards used to match test results against a reference scale for both freshwater and saltwater setups. To run a test, a water sample is added to the tube along with drops from each solution bottle, then the resulting color is compared to the printed chart. Written instructions accompany the kit to help interpret readings and outline steps for addressing elevated ammonia. The kit is intended for regular monitoring, particularly during the early weeks of setting up a new aquarium when biological filtration is still developing. No tools or assembly are needed beyond following the printed testing steps.
