Cal Aqua Labs Efflux F3 outflow pipe

The Efflux outflow pipe carries the unique downward-angled funnel design to provide increased water movement to lower parts of the aquarium. This reduces stagnation points and improves gas and nutrient exchange for low and mid ground plants

The funnel can be conveniently raised slightly above the waterline to create gentle surface movement which will eliminate surface film without aerating the water, and hence reduce CO2 loss. To aerate, simply life the funnel slightly higher.

The Efflux F3 has a 17 mm tube diameter for 5/8″ tubing and holds two suction cups for enhanced stability. The width between the arch is approximately 6 cm. The F3 is suitable for aquariums 30 gallons and larger that use 5/8″ tubing for the canister filter outflow. Each F3 pipe is supplied with two removable suction cups.
