Maxspect Jump Gyre Flow Pump MJ-GF308

The Maxspect Jump Gyre Flow Pump MJ-GF308 is a compact, high-performance cross-flow wavemaker designed to deliver powerful, evenly distributed water movement for reef and freshwater aquariums. Unlike traditional powerheads that create narrow streams of flow, the MJ-GF308 generates a true gyre current, producing broad, consistent circulation that eliminates dead spots and keeps detritus suspended for removal by your filtration system.

Perfect for nano to medium-sized reef aquariums, the MJ-GF308 features Maxspect's upgraded Jump controller, adjustable flow patterns, ultra-quiet sine wave technology, and innovative 360° flow directors, allowing you to customize water movement to meet the needs of SPS, LPS, and soft corals. It can also be linked with additional Jump Gyre pumps to create synchronized or alternating flow patterns for a more natural reef environment.

Why Choose a Gyre Flow Pump?

Traditional wavemakers create concentrated streams of water that often leave areas of poor circulation behind rockwork and near the substrate. The Maxspect Jump Gyre produces a broad sheet of water that travels the full length of the aquarium before returning along the opposite side, creating complete circulation throughout the tank.

This natural flow pattern helps:

• Deliver nutrients to corals

• Improve gas exchange

• Keep detritus suspended for easier filtration

• Reduce waste buildup behind rockwork

• Promote healthier coral growth and polyp extension

• Create more natural ocean-like water movement

Advanced Controller & Custom Flow Modes

The included Jump controller allows you to easily customize water movement with multiple operating modes, including:

• Random Mode

• Rapid Pulse Mode

• Slow Pulse Mode

• Gradual Speed Mode

• Constant Speed Mode

The controller also includes Feed Mode and wireless group synchronization, allowing multiple pumps to operate together in synchronized or anti-synchronized patterns for advanced flow customization.

Perfect for Reef Aquariums

Proper water movement is essential for healthy corals and efficient nutrient export. The MJ-GF308 provides broad, high-volume circulation that supports SPS, LPS, soft corals, and mixed reef aquariums while minimizing dead spots and improving overall aquarium health.
