Product Questions

How do these pumps do in terms of noise produced? And are these "Apex Ready", or "compatible with an Apex"?
Question by: David Hutchings on Jul 28, 2016 3:23:00 PM
Hi David,
The VarioS pumps are “Apex Ready” pumps and are very quiet just like all other DC pumps. On full blast you may hear the slightest bit of noise but if you turn the power down just one step they will become virtually silent.

Full Details

Efficient - Safe - Reliable

5 Flow Settings - Precise control of the pump for any application.

True Slow Startup - Easy on equipment and saves energy.

Detachable Controller - Waterproof union.

Float Switch - Creates a new standard for pump safety.

Rotatable Volute - Rotates in 90-degree intervals.

Integrated Memory - Keeps programming even during power outages.

Feed Mode - Shuts down for 15 or 60 minutes.

Submersible or External - Perfect as a return, closed loop, or reactor/filter pump.

Super Quiet Operation - Perfect for places where any noise is not tolerable.



The safe and energy efficient VarioS DC pump now include the new VarioS controller giving you more control. With 5 different energy saving speeds and two feed modes, the controller lets you know what your pump is doing at a glance.


Third Party Control

There is a dedicated port on the VarioS controller letting you directly connect your VarioS pump to any third party controller through a 0-10V reference port. Controlling your pump through a controller like an Apex lets you create your own flow profiles which are particularly handy for closed loop systems creating a random flow throughout the aquarium.



Having a pump that lets you directly attach a float switch has several advantages. The float can let you set high or low points in your sump, skimmer cup, or display tank that will shut the pump off when the float is activated.

The VarioS controller includes a waterproof 3-conductor union that connects to the pump creating a safe and detachable connection.

  • Awesome Pump! By Jason on 10/11/2016

    I am running this pump on my Red Sea Reefer 250, this pump is overkill but by the time you add plumbing for a manifold it is awesome! I wanted to go with the vetra M1, I decided on the VarioS-6 because it is apex ready out of the box and cheaper than the M1. Highly recommend!
  • Nice Pump By Rob on 9/30/2016

    Very quiet pump, its been running for about a month now.
  • Quiet! By Aaron on 9/13/2016

    Never thought I would find a pump that was silent until I found this one. Control features are great but the biggest advantages: First it's fully APEX Ready! Don't need to buy anything but a simple cable for the 0-10v port. Second, maybe the best thing, it's less than 300$ and don't need to buy other stuff to connect it to my APEX.
    Construction is quality, impeller and bearing are very stout.
    This is the best return pump you can get without spending twice or 3x as much.
  • So far so good By N.y. 78 on 8/28/2016

    I love the float switch feature wired into my main display so in case anything happens and the overflow does not work it will not continue pumping water into the main display the float switch will shut it off and the choice between 15 minutes and 60 minutes time is awesome
