Reef Octopus Varios-2 Review: Features & Benefits

Build Quality

This product is the ultimate representation of power and strength. Manufacturers added high-quality ceramic shaft and propeller bearing, which is very useful in terms of reducing any wear and tear.

It connects the pump and the controller with a water-resistant conductor, which is divided into 3-unions. So, it allows you to regulate the flow of water in two ways. It can be horizontal as well as vertical.

Besides, due to the detachable controller, you can rotate the volute in 90 degrees to change the orientation of the pump.

Super Quiet

It is challenging to work with a tool when it creates noise for no reason. In the case of your aquarium pump, it gets even more challenging to tolerate because we have to keep these devices turned on for a long time.

It starts very slowly and gradually speeds up over time (10 seconds per RPM).


Safety is always our first concern, and in this product’s case, it is maintaining a secure connection between water and electricity. This product ensures maximum safety with its unique model and design.

It comes with a float switch connection that correlates to the reef controller. So, it shuts off automatically under two conditions. One is when the waste box is jammed or full, and another is when the sump water approaches to very high or low intensity.

Furthermore, the controller is detachable and waterproof, so no worries regarding electrical units. Also, it runs in low-voltage, and with that, it prevents unnecessary heating.


Aquariums are not easy to maintain, but using suitable products can make it easier for us. Besides, there is always an issue related to electric bills and power units. Therefore, this product ensures the maximum energy-saving feature.

Instead of using AC, it uses DC, so it consumes less electricity. It consumes around 24V, which is consistently very low compared to any other power unit.

Therefore, it cuts down your electric bills with the maximum flow rate of 792gph in 13 ft height. Sometimes it varies considering your aquarium setup.
