Certified (#AQ0358037) Department of Agriculture


VarioS DC pinwheel skimmer pumps from Reef Octopus offer precise control, performance, and efficiency.

Over conventional AC pumps, DC skimmer pumps have a few significant benefits. The VarioS skimmer pumps offer near-silent operation in addition to allowing you to easily change the air and water flow rates via your skimmer. With this, you may adjust your skimmer’s effectiveness to correspond with the bioload in your tank and get the best waste removal. Additionally, these skimmer pumps come with a float switch that enables you to turn the skimmer pump off when the waste collector is full or when the water level in your sump is high or low.

The new VarioS controller, which gives you additional control, is now included with the secure and energy-efficient VarioS DC pump. The controller provides two feed modes and five energy-saving speeds so you can see at a glance how your pump is operating.

Third Party Control

The VarioS controller has a specific interface that allows you to easily connect your VarioS pump to any other controller using a 0-10V reference port. You may design your own flow profiles, get the greatest possible performance out of your skimmer, and integrate additional safety features of the controller by controlling your pump using a controller like an Apex.


A big benefit is having a pump that enables direct float switch attachment.
You may use the float to establish high or low positions in your sump, skimmer cup, or display tank so that when the float is engaged, the pump will turn off.

A watertight 3-conductor union on the VarioS controller connects to the pump to form a secure yet removable connection.
