API Freshwater Master Test Kit

The API Freshwater Master Test Kit is the most comprehensive liquid test kit available for freshwater hobbyists, testing pH, ammonia, nitrite, and nitrate from a single box. Each parameter uses a color-matching liquid reagent method that delivers accurate, repeatable results far superior to test strips. The kit contains enough reagent for over 800 individual tests, making it one of the most cost-effective options for regular water quality monitoring. Ideal for cycling new tanks, diagnosing fish health issues, and maintaining a stable, healthy aquarium environment. Comes with a detailed color chart, test tubes, and a clear instruction booklet.
