Designed for aquariums approximately 20 gallons and larger which use a canister filter with 1/2" diameter tubing. The outflow has an upward funnel shape which gently releases water into your aquarium. 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 midground 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 lift the funnel slightly higher.
Cal Aqua Labs glassware is hand-blown using only the highest quality, laboratory-grade, borosilicate glass for maximum strength, durability, and visual clarity. Each piece is unique.
