Aquarium Test Kits

Although aquarium test strips are quick and easy, they lack the precision of dedicated tests. A basic freshwater aquarium test kit should include an ammonia test, nitrite test, and nitrate test, which measure toxins from fish waste, and an aquarium pH test kit, which measures the acidity of the water. A saltwater aquarium test kit should include those plus an alkalinity test and calcium test kit. Proper alkalinity levels help maintain pH. Plus, coralline algae and corals take up calcium and alkalinity as they grow. A reef test kit may include many other tests for trace elements and minerals in fish tank water.

Hanna Checker testers take aquarium testing to the next level with digital precision.
