CALCIUM TEST KIT

Calcium is one of the most important elements in a reef aquarium. Reef invertebrates, such as corals, crustaceans, mollusks, and even some type of encrusting algae, need calcium to grow and remain healthy. Over time, the calcium level drops as it is used by invertebrates, or as it reacts with excess phosphate. The API CALCIUM TEST KIT measures calcium levels as low as 20 mg/L to help you keep your reef inhabitants healthy.

NITRATE TEST KIT

High nitrate levels in your aquarium indicate a build-up of fish waste and organic compounds, resulting in poor water quality and an increase in algae growth. Contrarily, maintaining a low nitrate level improves the health of fish and invertebrates.

Use the API® NITRATE TEST KIT to ensure that the nitrate levels in your tank are safe and healthy for your fish. The NITRATE TEST KIT reads parameters from 0 to 160 ppm and may be used for both fresh and saltwater aquariums.
