The flow is not very powerful, but they suite my applications and have performed well. An older picture shows how one of these pumps are being used to diffuse CO2 in a twenty gallon tank. The plastic filter chamber/case was removed from the pump, as well as the suction cups(that are used to secure the pump to aquarium)... also attached a black 45 degree fitting to the output directing the flow to the bottom of the tank, which the picture does not show. Very effective/efficient with dispersing and circulating CO2 mist.
