Product Overview

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
- Dead spots with relatively poor water movement.
- Very strong flow in the center, making coral placement very difficult.
- Very weak flow near the other end of the aquarium.
- Virtually no dead spots.
- Evenly distributed flow rate throughout the entire aquarium.
- Water bounces back from the other side to create a full circulation.ie.generating "gyre flows".
Electricity current alternates in a much smoother pendulum while using Sine Wave Technology
Integrated Controller with Large Display
Fully Programmable 24 hours gyre flow cycle

About The Manufacturer
Maxspect is an aquarium equipment company founded in 2009. A group of reef-keeping friends, tired of old-fashioned reef lighting set out to bring modern LED technology to the aquarium scene. They designed and built an LED aquarium light to prove the technology could support coral growth. Today Maxspect is a world leader in slim LED reef lighting fixtures. Maxspects’s mounting systems are simple and adaptable to any aquarium. The company is best-known for their gyre water movement pumps that simulate tide and wave patterns like those on natural tropical reefs. Gyre water flow ensures all of the water in your aquarium is circulating from top to bottom with no dead spots. The Maxspect gyre pumps use magnetic mounts for easy installation. The water flow pattern is set and managed by an advanced external controller.
