This kit allows for easy and accurate measuring of calcium levels to help in maintaining a healthy aquarium.

Why test for Calcium?
Monitoring calcium levels is essential for keeping a successful reef aquarium. Reef organisms use calcium to build a calcium carbonate skeleton. Over time, as the calcium in the water is utilized, the calcium level will gradually drop. Calcium must be present for corals to grow. Even reef invertebrates such as crustaceans, mollusks and encrusting algae, require calcium to grow and remain healthy.

Calcium levels drop 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 calcuim 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. Use Aquarium Pharmaceuticals Phosphate Test Kit to test for phosphate. If necessary, use Aquarium Pharmaceuticals Phos-Zorb™ to remove excess phosphate. Phos-Zorb is a special phosphate-removing filtration media that comes in a flow-through pouch. It conveniently fits into any filter.

Carbonate hardness (KH), often referred to as alkalinity, is important for reef organisms. As carbonate levels drop the pH becomes unstable. The carbonate hardness level (KH) should be 7-10 dKH [125 – 179 mg/L (ppm)] to encourage growth in a reef aquarium and maintain pH. Use the Aquarium Pharmaceuticals KH Test Kit to measure the carbonate hardness. Add Proper pH 8.2 to increase carbonate hardness and stabilize the pH to 8.2.
