Description
This is a product review for the Maxspect Mj-gf Gyre Flow Pumps. The gyre flow pumps are based on crossflow technology, which is superior to propeller nozzle technology. They come in two models, the MJ-GF2K and MJ-GF4K, and both have a dimension of L223 x W72 x H38mm and a weight of 457g/16.1oz. They are suitable for aquariums up to 50-250L/13-66 US Gal and 50-450L/13-118 US Gal, and have a flow rate of 7,000 L/H (1,849 US Gal/H) and 15,000 L/H (3,962 US Gal/H). They are supplied with a power supply unit that inputs 100-240V/50-60HZ and outputs 24V/2A and 24V/2.5A.

The Maxspect Jump series is designed to give aquarists an affordable and straightforward entry into the reefkeeping hobby. The new Jump Gyres have the same form factor, crossflow, and Sine Wave technologies seen in Maxspect's flagship Gyre series, but in a slightly smaller package and with an easy-to-use integrated controller.
The Maxspect Jump Gyre Flow Pumps incorporate Cross Flow technology to generate a "sheet" of water across your tank for improved overall water circulation. With Crossflow technology, the water even bounces back after reaching the other side of your aquarium, virtually eliminating any dead spots. Compared to other traditional propeller-style powerheads, the Gyre produces an even, linear flow that can reach across longer tanks without creating direct hot spots of flow.
The Jump Gyre Flow Pumps include an integrated controller that allows for full 24-hour flow cycle programming. You can choose from several different flow modes to run throughout various times of the day-- constant, pulsing, random, alternating, etc-- so you can dial in your circulation patterns to suit your reef tank's needs.
