API Ammonia Test Kit API Ammonia Test Kit is a freshwater and saltwater liquid test kit that measures ammonia from 0 to 8 ppm, helping aquarists detect one of the most dangerous invisible water-quality problems in aquariums. API Ammonia Test Kit for Freshwater and Saltwater Toxic Ammonia Monitoring Ammonia can enter aquarium water through fish waste, uneaten food, and decaying organic material. Even small amounts can stress fish, while high levels can be deadly. This liquid test kit helps monitor ammonia during aquarium cycling, after stocking changes, and whenever fish show signs of stress. Liquid Ammonia Testing from 0 to 8 ppm for New and Established Aquariums Measures ammonia levels from 0 to 8 ppm. Suitable for freshwater and saltwater aquariums. Includes separate freshwater and saltwater colour charts. Useful during new aquarium cycling and after filtration changes. Helps identify ammonia spikes caused by overfeeding, livestock loss, or biological-filter disruption. API recommends testing several times a week for 4-6 weeks when starting a new aquarium. After cycling, use weekly for monitoring or whenever problems occur.
