CO₂ Cylinders for Marine Calcium Reactors
Essential CO₂ Supply for Your Reef Aquarium
Keep your calcium reactor operating efficiently with our CO₂ Cylinders for Marine Aquarium Calcium Reactors.
Calcium reactors are a popular method of maintaining calcium and alkalinity in established reef aquariums, particularly systems containing growing populations of SPS and LPS corals.
By introducing a controlled supply of carbon dioxide into the reactor, the internal pH is lowered, allowing calcium carbonate media to dissolve and release calcium and alkalinity into the aquarium.
Our CO₂ cylinders provide the gas supply required for this process when connected to a compatible calcium reactor and regulator.
Key Features & Benefits
-
Designed for calcium reactor applications – Provides CO₂ for compatible marine aquarium calcium reactors.
-
Supports calcium and alkalinity supplementation – Enables controlled dissolution of calcium carbonate reactor media.
-
Ideal for demanding reef systems – Particularly useful for established SPS and mixed-reef aquariums.
-
Refillable cylinder option – A practical alternative to disposable CO₂ cartridges.
-
Compatible with suitable regulators – Allows controlled gas delivery when correctly connected to appropriate equipment.
-
Supports stable reef chemistry – Helps maintain consistent supplementation when the reactor is correctly adjusted and monitored.
How Does CO₂ Help a Calcium Reactor?
Inside a calcium reactor, carbon dioxide dissolves into the circulating water, lowering its pH.
This acidic environment gradually dissolves the calcium carbonate reactor media, releasing calcium and alkalinity into the water passing through the reactor.
The enriched water is then returned to the aquarium, helping replace minerals consumed during coral and coralline algae growth.
For reliable operation, the CO₂ supply must be carefully regulated to match the aquarium's consumption.
Installation & Safety
Always use a regulator designed for the cylinder's specific valve connection and operating pressure.
Secure cylinders upright, protect them from heat and physical damage, and check gas connections for leaks before use.
Please note: A compatible CO₂ regulator, solenoid valve, gas tubing and calcium reactor are not included unless specifically stated.
