The simplest, most technologically advanced carbon dioxide system available! The carbo-plus does not use pressure bottles or reaction chambers to add co2 to your tank. Simply place the carbon bar upright in the aquarium, set the desired carbon amount on the easy-to-read dial outside the aquarium, and the unit starts producing CO2 immediately! At maximum use, Carbo-Plus will product .29 grams of CO2 per hour.

Carbon dioxide is an essential component of healthy aquarium plant life. Adding carbon dioxide to aquarium water couldn’t be easier than with Carbo-Plus.



Carbo-Plus needs NO CO2 reactor, NO bubble counter, NO CO2 gas, NO pressure tank, gas refills or special tubing and the monitor even lets you know when it is time to replace the carbon block. Complete Carbo Block Holders (Item #517); Carbo Blocks Refills (Item #516) also available.
