API 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 types of encrusting algae need calcium to grow and remain healthy. Over time, calcium levels drop as invertebrates use calcium in aquarium water.This kit allows you to easily and accurately measure calcium levels and maintain a healthy reef aquarium. Features of the API Calcium Test Kit Measures calcium levels as low as 20mg/L Uses titration method, with easy to see color change for precise measurement. For use in reef aquariums

API Ammonia Test Kit The API AMMONIA TEST KIT measures ammonia to help prevent fish loss, as ammonia is the number one stressor and killer of tropical fish.Ammonia is released into an aquarium in the forms of uneaten food, decaying organic matter, and when fish release it through their gills, urine, and solid waste. The API AMMONIA TEST KIT is a mercury-free, salicylate test for fresh and saltwater fish, and measures ammonia levels from 0 to 8 ppm.

API Nitrate Test Kits 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.

API Alkalinity (KH) Test Kit The API KH TEST KIT tests fresh or saltwater aquariums for carbonate hardness (KH), and helps monitor water quality and prevent invisible water problems that can be harmful to fish and plants. Carbonate hardness stabilizes aquarium pH, and can be used to determine the proper dose of pH buffers.

API Phosphate Test Kit Phosphate can enter your aquarium through tap water, fish waste, and decaying organics such as uneaten food and dead algae. Excess phosphate contributes to unsightly algae and green water blooms, and in saltwater, excess phosphate can inhibit the growth of hard corals. The API PHOSPHATE TEST KIT tests phosphate levels from 0 to 10 ppm so that you can easily monitor the condition of your aquarium water and may be used in both fresh and saltwater aquariums.

API Nitrite Test Kits Nitrite is produced in the aquarium in the forms of fish waste, uneaten food, and by nitrifying bacteria in your aquarium's natural cycle as it breaks down ammonia. Low levels of nitrite inhibit respiration and suppress the immune system, while high levels cause suffocation in fish. The API NITRITE TEST KIT reads nitrite levels quickly and accurately in your tank, and tests parameters from 0 to 5 ppm.
