Golden Angel Co2 Diffuser, Carbon Dioxide Mixer For Planted Aquariums

The diffuser is fixed to the intake-side of the aquarium circulation pump or filter, hence the mixed gas (CO2) is held in contact under pressure within the pump or filter chamber till the gas/water mixture exists the outflow end; thus enabling efficient mixing of the gas with the liquid. The gas itself is passed through an air diffuser before contacting the liquid thereby increasing the mixing efficiency.
