Live Rock N Reef offers a great selection on CO2 equipment including CO2 regulators, CO2 cylinders, CO2 reactors, tubing, test kits and more for your freshwater or saltwater aquarium. 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 reactors effluent in order to dissolve hydro carbonate media into bio-available calcium molecules. Calcium is then utilized by corals and other marine organisms mainly for skeleton building.
