VERY IMPORTANT!
One pump per controller
It is not possible to connect 2 pumps to one controller.
Not compatible with Gyre Series pumps.
Jump pumps and controllers are not compatible with Gyre Series pumps and controllers and vice versa.
Incompatibility with Gyre Series spare parts.
Jump spare parts are not compatible with Gyre Series spare parts and vice versa.
Thanks to its cross-flow technology, it provides an even flow distribution, thus avoiding dead zones in the aquarium. Maxspect Jump MJ-GF pumps excel in moving water from one side of the aquarium to the other. The resulting current is strong enough for the water to reach the other side, creating a continuous circulation in the aquarium, i.e. a gyre flow.
Silent thanks to the use of sine wave technology from the Turbine Duo!
Controller with a large display allows you to program 24 hours Gyre flow cycles .
Different water movement modes :
Constant speed mode, pulsing mode, gradual pulsing mode, random mode, alternating gyre mode.
MJ-GF Series
Superior Cross Flow Technology Explained
Comparing to traditional powerheads and wavemakers, based on propeller nozzle technology, our latest gyre generator is based on crossflow technology.
Propeller Nozzle Technology
  ①  Dead spots with relatively poor water movement.
  ②  Very strong flow in the center,making coral placement very difficult.
  ③  Very weak flow near the other end of the aquarium.
Cross Flow Technology
  ①  Virtually no dead spots.
  ②  Evenly distributed flow rate throughout the entire aquarium.
  ③  Water bounces back from the other side to create a full circulation.ie.generating “gyre flows”.
