The API® SALTWATER MASTER TEST KIT measures the 4 most important saltwater parameters – pH, ammonia, nitrite, and nitrate – to enable easy testing of your tank’s natural cycle, and to aid in maintaining a thriving saltwater aquarium. Testing is fast, easy, and accurate, yielding precise results, and comes with 4 test tubes and a convenient holding tub for easy storage.
