Find the colour chart on the back to compare your results and this will tell you how much of these parameters are in your water. This test strip is designed with the aquarist in mind; beginner and experienced, and yields the reliability that an expert can count on.

Ideal Pond Water Parameters

Pond & Aquarium water parameters are often overlooked. Yet, having the correct pond & aquarium water parameters is one of the most important factors for a successful, healthy pond & aquarium. Correct parameters mean your fish will be healthy. Aerobic bacteria can do their job properly. Finally, any pond and aquarium plants added will contribute positively to the condition of the pond or aquarium. It is not possible to know the condition of pond or aquarium water without testing it, so regular water testing is the only way to protect the health of all pond and aquarium life from deteriorating water conditions. If your water is cloudy, green, or discoloured, there may be a serious problem with your water conditions. Test your pond or aquarium water immediately to solve the problem fast and efficiently.
