Maxspect XF150 Gyre Generator Revolutionary Crossflow Water Movement Technology After months of anticipation, the Maxspect Gyre—the world's first gyre-generating water moving device for aquariums—is now in stock! Compared to traditional powerheads and wavemakers based on propeller nozzle flow technology, the Maxspect Gyre uses advanced crossflow technology which produces massive horizontal water movement, leaving little to no deadspots in its wake. The 50 watt Gyre has a max flow rate of 5,000 gallons per hour and is rated for tanks from 50 to 800 gallons. The Gyre can be placed horizontally or vertically to evenly distribute flow throughout the entire aquarium; water bounces back from the other side to create a full circulation to generate the "gyre flow." The Gyre comes packaged in a handsome black metal box that contains the Gyre pump with magnet mount, controller with mountable craddle, power supply, spare rotors and cages. The Gyre is also backed by a generous 12-month manufacturer warranty. Place your order now to reserve a unit in our first shipment while supplies last!

BONUS: The Gyre ships FREE within the U.S. and includes a T-shirt in the print and size of your choice!
