CarbonDoser Electronic CO2 Regulator, Version 2

The CarbonDoser is an electronic CO2 regulator for planted freshwater aquariums and for calcium reactors on saltwater systems. Instead of a needle valve, it uses an electronic valve that opens and closes to produce each bubble.

• Electronic valve in place of a needle valve
• Each open and close of the valve equals one bubble
• Designed to hold the set bubble rate steady
• Suits planted freshwater tanks and calcium reactors
• Version 2

Read the manual before setup, and check all connections for leaks when you attach the regulator to your CO2 cylinder.
