CO2 (Carbon Dioxide) is useful both in freshwater and marine environments. 
In the freshwater aquarium, CO2 enhances your ability to successfully keep live aquatic plants.  As green plants photosynthesize, they utilize carbon dioxide. Without CO2, live aquarium plants will have a hard time thriving in the closed aquarium system.
In the marine aquarium, CO2 is used to lower the pH of calcium reactor effluent in order to dissolve hydrocarbonate media into bio-available calcium molecules. Calcium is then utilized by corals and other marine organisms mainly for skeleton building.

At AquaCave, we offer some of the best selection and best prices on CO2 accessories including CO2 regulators, CO2 Tanks, CO2 solenoid valves, pH controllers, CO2 reactors, CO2 diffusers and needle valves for your marine, reef, and freshwater aquarium.
