HYDROS WaveEngine Direct Drive Compatible

The HYDROS WaveEngine is a multi-brand, multi-pump controller. It allows you to control, monitor, and power pumps from different brands together using a single app. Finally, pumps from different brands can work together under a unified platform!

In addition to wireless and 0-10V control, the WaveEngine has the ability to control and power up to 4 pumps. Using the Direct Drive ports on the front of the WaveEngine, you can plug in pumps from different brands like IceCap, Reef Octopus, and Maxspect so you can power 4 pumps off a single power supply. By utilizing the Direct Drive ports, you no longer need the external controllers that are included with these pumps. If you're using 4 pumps, imagine all the clutter you can clear out of your stand by not having to use 4 power bricks and 4 controllers and instead having one of each.

Due to the growing popularity of the WaveEngine, brands like IceCap are offering "pump only" versions of their products that do not include the external controller and power supply. Now, for a much lower price (you'll save $100!), you can purchase just the pump itself and the mounting base so you can directly connect the pump to the WaveEngine. All you will need is the appropriate adapter, in this case, the HYDROS IceCap Gyre WaveEngine Pump Adapter, and you'll be able to do things with flow that you never thought possible!

The Gyre 4K Uses Revolutionary Crossflow Technology

Wavemakers excel in making waves, while waves are spectacular to watch in motion, they are moving the majority of the water vertically up and down, with relatively low horizontal movement, especially near the bottom of the aquarium.

On the other hand, gyre generators excel in moving the sheer flow of water from one side of the aquarium to the other. The flow of water is so strong that it would bounce back from the opposite side to achieve full circulation within an aquarium, i.e., generating "gyre flows."

Why have Gyre pumps taken the aquarium world by storm? There are three main reasons: 

  1. They leave virtually no dead spots in your aquarium.
  2. The flow is evenly distributed throughout your entire aquarium.
  3. Water bounces back off the other side of your tank, creating a full circulation to complete the Gyre pattern.

These three key points run in stark contrast to the performance of the status quo propeller-type pumps that once ruled the hobby. Sure, they can move water. But they don’t do it as efficiently and intelligently as the Gyre! For example:

    Standard Propeller Flow Technology

Disadvantages of Standard Propeller Nozzle Pumps

A) Relatively weak water movement with dead spots left in their wake.

B) There is a powerful flow in the center but not elsewhere, which makes coral placement difficult.

C) The water movement is weak at the other end of the aquarium and is not designed for recirculation.

Why is a Gyre Generator Superior to a Wavemaker?

Wavemakers excel in making waves. While waves are spectacular to watch in motion, they are moving the majority of the water vertically up and down, with relatively low horizontal movement—especially near the bottom of the aquarium.

On the other hand, the Gyre excels in generating massive movements of water from one side of the aquarium to the other. The sheer volume of water is so substantial that it bounces off the opposite side of the aquarium to achieve full circulation within the tank. Or, as we call it, generating a “gyre flow.”
