This easy-to-use liquid test kit helps you adjust your water parameters for the success of your reef aquarium. Measures four essential water parameters. Long-lasting kit contains tests for calcium (70 tests), carbonate hardness (number of tests varies by water hardness), phosphate (150 tests), and nitrate (110 tests). Included instructions explain how to use the tests in an easy-to-understand manner for precise test results. Kit contents: 7 test bottles, instruction booklet, 4 glass test tubes, and 2 color cards. Refills available for Calcium & Carbonate Hardness, Phosphate, and Nitrate.
Saltwater Master Test Kit available for general marine aquarium testing.

Calcium Test Instructions
Why Test for Calcium?
Calcium level drops as it is used by invertebrates or as it reacts with excess phosphate. Making a partial water change may help to maintain proper calcium levels, depending on the brand of salt mix. Special calcium additives are also available. Elevated phosphate precipitates calcium, rendering it unavailable to reef organisms. Phosphate enters the aquarium from tap water and as a byproduct of fish and invertebrate metabolism. If necessary, remove excess phosphate. However, just having an adequate calcium level is not enough to achieve healthy coral growth, because the growth of corals is directly linked to carbonate hardness (KH), often referred to as alkalinity. All reef organisms rely on the combination of calcium and carbonate to build their skeleton structure by extracting these substances from saltwater. These two building blocks are essential for the growth of corals, crustaceans, mollusks, coralline algae and calcareous forms of macroalgae. Testing for both carbonate hardness and calcium is essential for successful reef keeping.

Phosphate Test Instructions
Why Test for Phosphate?
In reef aquariums, phosphate precipitates dissolved calcium and magnesium ions, inhibiting the growth of hard corals and other reef-building organisms.
