Unbalanced pH levels, resulting from fish waste and the build-up of natural acids, are unhealthy for fish. Use kit to measure and correct pH levels for a healthy African cichlid, marine, or goldfish aquarium. Kit comes with one high range pH test solution bottle, one instructional booklet, two color cards, and one capped glass test tube.

Most water problems are invisible to the eye. Quickly measure and modify the six aquarium levels that are most important to the health of your freshwater fish. To stay healthy and thrive, fish need properly balanced levels of ammonia, pH, high range pH, nitrite and nitrate. These levels can change rapidly and create harmful conditions when fish waste, uneaten food or other organic matter accumulate, or when untreated water is added.
