A compact and efficient CO2 diffuser designed to be powered by a seperate pump, for example to be installed on the return feed from an external filter. Ideal for planted aquariums up to 750 litres.
CO2 bubbles enter at the bottom of the cyclo chamber and rise, collecting under the steps of the turbo attachment. Water coming from the filter outlet or a seperate pump whirs downwards past the pockets of CO2. This counter-current effect ensures the CO2 dissolves into the aquarium water very quickly, and the CO2-rich water then flows into the aquarium from the bottom of the whirl chamber.
