Highly concentrated calcium and alkalinity powder

Tropic Marin® Carbo calcium Powder is highly concentrated calcium and alkalinity for dissolving in reverse osmosis water to get the proven Carbo-Calcium solution. After dissolving, one single solution can cover all the calcium and

carbonate hardness requirements of a typical reef aquarium without undesirable additional compounds or excess carbon dioxide being produced. This ensures strong growth of corals, coralline algae and other reef organisms. 100 g (3.5 oz.) of Carbo calcium Powder containing more than 30,000 mg of calcium and more than 4,000°dKH.

This high-yield product is suitable for all tank sizes and prevents the side effects of other methods of calcium hardness: the pH remains stable; there is no excess CO2 and there is no risk of unwanted phosphates being introduced through coral breakage. In addition, there is neither a creeping increase in salinity, nor increased oxygen consumption through carbon compounds. After mixing, the resulting solution is suitable for both manual dosage and for dosing pumps.

 Benefits:

•Extremely high yield: 700g Carbo calcium contains 215 g calcium and > 30,000 alkalinity (°dH)

•The pH value remains completely stable

•No phosphates or surplus CO2 are added to the aquarium

•The salinity remains constant(no sodium chloride is created)

•No danger caused by oxygen depletion

•Suitable for all tank sizes

•After mixing, the resulting solution is suitable for both manual dosage and for dosing pumps.

How to use:

The 700 g (1.5 lbs.) can of Carbo calcium Powder is sufficient for 5 l/1.3 US-gal. liquid solution, the 1400 g(3 lbs.) can for 10 l/2.6 US-gal. liquid solution.

6 level measuring spoons (approx. 140g/5 oz.) of Carbo calcium Powder are dissolved in 1 l/0.26US-gal. reverse osmosis water to create the liquid mineral solution. This solution has a long shelf-life and contains 43,000 mg of calcium and 6,000 °dH.

You can now start with daily doses of 5ml of the mineral solution for every 100 l/26 US-gal. aquarium system volume.Monitor the alkalinity level as you increase the daily dosage by 2.5 ml for every 100 l/26 US-gal. aquarium system volume every week until you reach a constant alkalinity level of 7 to 9 °dKH.

Maximum dose: 25 ml per 100 l/26 US-gal. aquarium system volume daily.
