Cal Aqua Labs' Fluxus System consists of an Influx pipe transporting water from the aquarium to an external filter, and an Efflux pipe bringing clean water from the filter back to the aquarium. Both pieces are made with the highest quality laboratory-grade borosilicate glass and artistically hand-blown.

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.

Supplied with necessary amount of suction cups.


  • Highest quality laboratory-grade borosilicate glass and artistically hand-blown
  • Downward-angled funnel design to provide increased water movement to lower parts of the aquarium
