Highly concentrated calcium and alkalinity
Tropic Marin® Carbo-Calcium Powder is highly concentrated calcium and alkalinity for dissolving in reverse osmosis water to get the proven Carbocalcium solution. After dissolving, one single solution can cover all the calcium and alkalinity 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.
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.
Extremely high yield: 1 kg (2.2 lbs.) contains 307 g calcium and approx. 43,000 °dH (alkalinity)
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
Contains organic calcium salts. After mixing, 1000 ml of the solution contain approx. 43,000 mg calcium and 6,000 °dH.
Application & Dosage
Before starting use of Tropic Marin® Carbo-Calcium as a supplement for your aquarium, it is recommended to adjust your systems calcium and alkalinity to your desired values. We recommend using Tropic Marin® Original Balling - Part A (calcium chloride) for the calcium and Tropic Marin® Original Balling - Part B (sodium bicarbonate) for the alkalinity.
Preparation of the solution from powder:
The 700 g (1.5 lbs.) can of Tropic Marin® 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.
To prepare the liquid mineral mixture, dissolve 6 level scoops (approx. 140 g) of Tropic Marin® Carbo-Calcium Powder in approx. 900 ml of reverse osmosis water, resulting in a total of 1 l of dosing solution.
Start with a daily dose of 5 ml of Tropic Marin® Carbo-Calcium per 100 liters (26 US-gal) of aquarium system volume. Increase the daily dosage weekly by 2.5 ml per 100 l (26 US-gal) aquarium volume until you reach constant alkalinity and calcium concentrations.
Once the dosage is established, and the system parameters are stable, measuring either calcium or alkalinity, on a regular basis will monitor your systems changes and needed dosage adjustments. The corresponding parameter only needs to be monitored periodically. We recommend using Calcium as the dosage regulator, as conventional test kits are more sensitive (or accurate) in measuring changes in the calcium concentration than changes of the alkalinity from Tropic Marin® Carbo-Calcium.
We recommend not to exceed a daily dose of 25 ml of Tropic Marin® Carbo-Calcium per 100 liters (26 US-gal) of aquarium system volume.
In some cases, calcium and alkalinity may be consumed in different ratios than from the coral’s needs alone. If this occurs, and parameters become unbalanced, use the chart to make the proper corrections.
