    Concentrated Calcium & Alkalinity for Advanced Reefers!

    Tropic Marin Carbo-Calcium contains a balanced ratio of calcium and carbonate (alkalinity) in a single solution. Traditionally two or more solutions are required but Carbo-Calcium relies on biological processes to release calcium and carbonate from a single liquid without the worry of precipitation or oxygen depletion. There are no by-products or unwanted excess CO2, phosphates, nitrates, or other pollutants while keeping a stable pH. 

    • A little powder makes a lot of liquid
    • Easy to mix with RODI water
    • Maintains proper ionic balance
    • Doesn't increase salinity (no sodium chloride)
    • Single solution for calcium & alkalinity
    • Suitable for all size aquariums
    • No byproduct formation
    • Suitable for all types of corals
    • Easy to use 
    • Dosing pump ready once mixed


    Two Sizes Available:

    • 700 g
    • 1400 g




    • The 700 g (1.5 lbs.) can of Carbocalcium Powder is sufficient for 5 liters (1.3 gallons) liquid solution, the 1400 g (3 lbs.) can for 10 liters (2.6 gallons) liquid solution.
    • 6 level measuring spoons of Carbocalcium Powder are dissolved in 1 liter (0.26 gallons) reverse osmosis water to create the liquid mineral solution.


    • Starting with a daily dose of 5 ml of Carbo-Calcium liquid solution per 100 liters (26 gallons) of total system volume. Increase the daily dose by monitoring the alkalinity. Increase the dose by 2.5 ml per 100 liters until a constant alkalinity of 7-9 dKH is achieved. 


    Note: In larger systems, Carbo-Calcium Powder can be added directly to a high flow area of your tank without any pre-mixing.


    Maximum daily dose - 25 ml of Tropic Marin Carbo-Calcium per 100 liters.
