Salifert

Salifert is a well-known aquarium test kit brand that produces a comprehensive line of water testing kits designed for marine, reef, and advanced freshwater aquariums. Their kits are recognized in the hobby for accuracy, ease of use, and reliability, covering key water parameters such as calcium, alkalinity, magnesium, nitrate, phosphate, pH, ammonia, and more — allowing aquarists to monitor and maintain stable water chemistry essential for fish, corals, and plant health. Salifert kits typically use colorimetric and titration methods, where color changes or reagent drop counts indicate parameter levels. This makes them popular with both beginners and advanced hobbyists who want manual, trustworthy test results without electronic meters.
