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.
Cross Flow Technology
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
Sine Wave Technology Decibel Level
Electricity current alternates in a very sharp pattern while using traditional Technology
