It is built for aquarists who want powerful, fully programmable water movement with simple control. Explore more reef pumps and equipment.

Wide, Laminar Gyre Flow

Crossflow technology sweeps water evenly across your aquascape and bounces it off the far glass to create a full gyre. That broad, laminar movement reduces detritus buildup, keeps nutrients suspended for export, and gives corals and fish the consistent flow they love. Mount it vertically or horizontally to shape the gyre to your tank.

Onboard Digital Control

The included controller offers five flow modes, constant, gradual speed, slow pulsing, rapid pulsing, and random, plus a feed mode and adjustable speed with 24-hour scheduling. Use the Group Leader and Group Member settings to link up to 32 pumps for synchronized or anti-sync flow across a larger system.

Tunable, Coral-Safe Flow

The included flow director cages and mesh guards let you aim and soften the output for sensitive LPS and soft corals without losing reach, while the strong magnet mount holds firmly on glass up to 20 mm thick. Quiet, low-vibration DC operation draws just 45 watts.
