1. A device for dispensing CO2, that is to say carbon or carbon dioxide, which can be fitted in aquariums or containers for holding live fish, the device comprising a dispenser casing or body, wherein the dispenser body is equipped with a mixing chamber into which a flow of water is delivered by a pump and a flow of CO2 from an infeed duct; the mixing chamber being bordered by at least one filtering element which occupies the lower half of the dispenser body, which can also be closed by a mesh cover, wherein said flow of water delivered by the pump through the inlet duct, placed in a substantially horizontal position inside the mixing chamber, is substantially at right angles to a CO2 injector attached to the infeed duct, which is, instead, arranged vertically with the gas delivery zone positioned in correspondence with the water output zone.
