Aqua Medic Reactor 1000
Aqua Medic CO2 Reactor 1000 features a hermetically sealed external reactor to ensure more efficient CO2 delivery by mixing water and CO2 through and around its Bactoballs before diffusing it into your aquarium. This means more CO2 will be dispensed into the aquarium and less will escape out the top of the aquarium. Saves on your supply of CO2; you'll fill less often. Aqua Medic CO2 Reactor 1000 measures 3" in diameter and 15" long.
