The API® Freshwater Master Test Kit measures the 4 most important levels in freshwater aquariums quickly and accurately, including pH, high range pH, ammonia, nitrite, and nitrate. With scientific accuracy for professional results, the reusable Freshwater Master Test Kit comes with 4 glass test tubes with snap-tight caps and a convenient holding tub for easy storage. 

The API® Saltwater Master Test Kit measures the 4 most important saltwater parameters – pH, ammonia, nitrite, and nitrate – to enable easy testing of your tank’s natural cycle, and to aid in maintaining a thriving saltwater aquarium. Testing is fast, easy, and accurate, yielding precise results, and comes with 4 glass test tubes with snap-tight caps and a convenient holding tub for easy storage.

The API® Reef Master Test Kit test 4 key parameters – calcium, carbonate hardness, phosphate, and nitrate – to keep reef inhabitants healthy. Testing is fast, easy, and accurate, yielding precise results, and comes with 4 glass test tubes with snap-tight caps and a convenient holding tub for easy, reusable storage. 

The API® pH Test Kit monitors pH to maintain healthy freshwater conditions in your tank. pH control is imperative to prevent the harmful effects of overly alkaline or acidic aquarium water on fish and plant life, so take a few minutes each week to maintain and monitor your pH conditions with this easy-to-use kit! Tests read pH from 6.0 – 7.6, and will help you quickly and easily determine whether your levels are too high or too low. 

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 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.

API® 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 contains 2 bottles of liquid test reagent, 2 color cards for easy comparison, 1 glass test tube with a snap-tight cap, and step-by-step instructions on how to correct unsafe conditions. It may be used for both fresh and saltwater aquariums. 

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 levels ammonia levels from 0 to 8 ppm.
