Calcium Powder


Calcium is essential for all life and form of cell walls, bones, and skeletons of many marine animals. It is very important in controlling important metabolic functions including regulation of cellular activity. Proper calcium and carbonate maintenance and management is very important for marine animals, fish as well as corals and other invertebrates.

*Deep Ocean Calcium Powder uses pure USP grade calcium in a low concentrated blend of balanced ions. Designed for hobbyist who want to maintain the utmost stable systems to provide optimum coral growth and health.

*Having ionic calcium levels found in natural seawater available at all times in a form that is readily absorbed by corals with little physical work  means more energy available for skeletal growth.

*Deep Ocean Calcium Powder recommends keeping levels to that of natural seawater, which has an average of about 412 ppm of calcium. It is not necessary to maintain high levels of calcium, in fact coralline algae and corals can have magnificent growth rates with calcium levels as low as 412 ppm.

*Excellent calcium source for all corals (Lps & Sps), coralline algae, snails, hard tube worms, and clams.

*Intensive boost to your coral´s color and growth.

*For all marine aquariums.

*Prevents deficiency symptoms of calcium ion.

*Free of nitrate & phosphate.


Basic: Dissolve 2.5 grams  of  Deep Ocean Coral Reef Calcium Powder per 20 US-gallons of aquarium water in 250 ml of fresh water; add every other day or as needed to maintain the Calcium concentration within a range of 412 - 450  ppm.

Advanced: Create a stock solution by dissolving 20 grams of Deep Ocean Coral Reef Calcium Powder in 250 ml of fresh water (preferably purified)each ml of the solution will increase Calcium concentration [Ca2+] in 1 US-gallon (3.785 L) of water by 6.57 ppm.

Reference: Each gram of Deep Ocean Coral Reef Calcium Powder will increase the [Ca2+] in 1L of water by 310.73 ppm.
