At AquaCave, we offer some of the best selection & best prices on Vortech Propeller Pumps by EcoTech Marine for you marine, reef, and freshwater aquarium.
The VorTech minimizes the intrusion of equipment in your tank by using a patent pending bracketless design; this allows the motor to be on the outside of the aquarium and uses a magnetic field to transfer torque through the aquarium wall to the propeller located in the water.
