Tropic Marin Carbo-Calcium is a highly concentrated calcium and alkalinity powder, that when mixed with reverse osmosis water, the resulting solution is suitable for manual dosage or dosing pumps.
A single mixed solution fully covers the calcium and carbonate hardness most reef aquariums consume. The mixed Carbo-Calcium solution does not contain undesirable additional compounds or excess carbon dioxide being produced, and will ensure strong growth of corals, coralline algae and other reef organisms.
Suitable for all tank sizes, Carbo-Calcium keeps pH stable, with no excess CO2, nor risk of unwanted phosphates being introduced through coral breakage. In addition, dosing will not increase salinity over time, neither increased oxygen consumption through carbon compounds.
BENEFITS:
Extremely high yield: 700g Carbo-Calcium contains 215g calcium and more than 30,000°dkH
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
Solution has a long shelf-life
SPECIFICATIONS:
100g (3.5 oz.) of Carbo-Calcium Powder contains more than 30,000 mg of calcium and more than 4,000°dkH
700g mixes to 5 liters (1.3 gallons) liquid solution
HOW TO USE:
Mix 6 level measuring spoons of Carbo-Calcium Powder to dissolve in 1 liter (0.26 gallons) reverse osmosis water to create the liquid solution
Start with a daily dose of 5 ml of the solution for every 100 liters (26 gallons) of aquarium system volume
Monitor the alkalinity level as you increase the daily dosage by 2.5 ml every week until you reach a constant alkalinity level of 7 to 9°dkH
Daily maximum dose: 25 ml per 100 liters (26 gallons) aquarium system volume
A dosing calculator for the liquid Carbo-Calcium solution can be found HERE
Available Sizes: 700g (1.5 lbs) and 1400g (3 lbs) cans

PROS
Simple. No need for extra room for more equipment. No danger of overdosing.
CONS
Have to add a scoop a day (like feeding your fish).

I have been adding a half scoop to the overflow of my 90 gallon system every morning for 6 months. A Montipora capricornis frag has tripled in size and a hammer coral has sprouted 4 new branches. This is so much safer than dosing kalk. I have previously had two kalk overdose disasters from a topoff pump sticking in the on position. There is no room left under my tank for adding a calcium reactor, a kalk stirrer or 2 large jugs of 2 part. Adding dry carbo calcium once per day is simpler, safer and cheaper for me.Hide
PROS
Easy to mix. Clean. Cost effective. Easy on equipment.
CONS
Takes a little patience to dial in. Does not test as easy as normal alk.

Just starting to get this dialed in. I like the idea of a small dose of a single product for Alk and Cal. Very concentrated so small doses are required.

Just starting to get this dialed in. I like the idea of a small dose of a single product for Alk and Cal. Very concentrated so small doses are required. Not as cost effective as Kalk but much cleaner and my top off is just plain Rodi now. Better for my top off pump. Carbo calcium is much more concentrated than Kalk. 1 liter for my 50 gallon tank lasts for a couple months. Powder mixes up clean and clear. I have seen zero precipitation. No adverse on fish or corals at all.Hide
Cheap and easy way to maintain alk and cal for my system. Just mix with RODI. Fair warning...it doesn't appear to mix completely and leaves leftover powder at the bottom but it doesn't appear to affect anything at all. Dosing this with TM trace elements as well. You can mix it all together for ...Read More
