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.

  • Runs quiet and overall very happy By Landon on 8/23/2016

    I finally decided to upgrade to a DC pump because my running noise was too loud with my Lifeguard Quiet One pro 2200. I chose this Reef Octopus Varios-2 because it was in my (under $200) price limit and the reviews for the Waveline DC pumps were not all that positive. I also liked the added bonus of the float switch which I installed on my display tank and after testing it I realize what an important feature this is...You know, in case my RBTA goes for a stroll and blocks my overflow. I have a 55Gal tank with a 20Gal sump and I know this pump is overkill (I only have it set on the 2 out of 5 speed) but it allows me to upgrade and I couldn't be happier with it! It's sooooo much quieter that my old one, I even took before and after videos and the noise difference is extremely noticeable. I have only been running it for a week now, so I can't speak to it's longevity, but I can see that it was built well and I'm completely satisfied so far!
  • Excellent pump so far! By ae86oni on 8/20/2016

    I have the skimmer version of the VarioS 2 pump. It is awesome so far! Dead silent and pulling skimmate like a boss! Can't even hear the thing running. Using it as a replacement for the 2x failed Sicce Syncra Silent 2.0 on my Aquamaxx skimmer (the Shark 2.0 pump as they call their modified version)
    Will also be replacing the MAG 7 return pump with one of these very soon! The aquarium will finally be quiet.
