A powerhead that answers all your needs: Extreme flow (~4000+ gph) Compact size (less total mass compared to nearly all similar flow pumps) Directional flow (pivots with 40 degree range of motion and can be rotated – great for rear wall use) Safe, 24V DC operation Low power consumption – <35W at the wall Multiple operational modes (random flow modes, mirror, inverse, etc.) Easy to clean (pump automatically shuts off when removed from water) Incredibly Quiet (possibly the quietest driver on the market) Magnetic mount works on up to 1″ glass (in a class by itself) Easy installation with just a single skinny wire for all power and control (1LINK interface makes it a snap!)
