Circulation Made Easy: Reef Octopus VarioS 4 Controllable Circulation Pump

Here's Why the Pros Choose Reef Octopus VarioS 4

The Reef Octopus VarioS 4 Controllable Water Pump is a state-of-the-art circulation pump that includes a detachable controller with mount, a high-quality ceramic shaft with propeller bearing to minimize wear and tear, and cutting-edge variable speed flow technology for refined control, enhanced performance, energy efficiency, and safer operations.

Advanced Technology of the Reef Octopus VarioS 4

Unlike most circulation pumps that use alternating current (AC), the VarioS 4 operates on direct current (DC), providing several advantages such as greater energy efficiency, safer low-voltage operation, and reduced heat production per volume of flow.

Offering Full Control for a Tailored System

The VarioS 4 allows aquarists to have complete control over water flow through their sump, reactors, filters, or closed-loop systems. The innovative VarioS Controller enhances pump control with features including:

  • 5 different speed settings
  • Float switch connection for high or low water level shutoff
  • Two pause/feed modes (15 or 60-minute intervals)
  • 0-10v input for 3rd party controller integration (e.g., CoralVue HYDROS Control X4/X10, Neptune System’s APEX, or Reef Angel)

Enhanced Features of Reef Octopus VarioS 4:

  • True slow startup: ramping up from zero RPM to full speed over 10 seconds
  • Waterproof 3-conductor union connection between pump and controller
  • Rotatable volute for adjustable output orientation in 90-degree intervals

Applications for Reef Octopus VarioS 4:

  • Freshwater and Saltwater Aquariums
  • Sumps
  • Reactors
  • Filters
  • Closed-loop systems

What's Included with the Reef Octopus VarioS 4?

  • VarioS 4 pump
  • Controller
  • Float switch
  • Power supply
  • Output and input union for plumbing direct PVC
  • Versatile stepped barb output fitting for flex tubing
  • Protective intake screen

What is an aquarium water pump?

An aquarium water pump is a device that circulates water within an aquarium. It is essential for creating water movement, oxygenating the water, and supporting filter systems.

Why should i use a water pump?

  • Water circulation: Prevents stagnant water areas and improves oxygen levels.
  • Filter support: Drives water through filters for efficient waste removal.
  • Powerhead function: Can be used to create water currents and simulate natural environments.
  • Equipment operation: Provides water flow for other aquarium equipment like protein skimmers or canister filters.

How do i choose the right water pump?

  • Tank size: Select a pump with appropriate flow rate for your aquarium.
  • Pump head pressure: Ensure the pump can lift water to the desired height.
  • Energy efficiency: Consider the pump's power consumption.
  • Noise level: Choose a pump with a quiet operation.

Flow Rate:

The pump should be able to circulate the entire volume of water in the tank 3–5 times per hour. For example, a 75-gallon reef tank would need a flow rate of 225–375 gallons per hour (GPH). For fish-only tanks, some recommend a flow rate of 10–12 times the tank's water volume, while mixed reef tanks and SPS tanks may need 15–20 times and 20–25 times, respectively.

Head pressure:

The pump will need to operate against a certain amount of pressure, which can be calculated by adding 1 foot of head pressure for each vertical foot, elbow, and every 10 feet of horizontal pipe. For example, if water needs to be pumped 4 feet vertically, through 2 elbows, and 10 feet horizontally, the pump will be under about 7 feet of head pressure.

What kind of maintenance should i expect?

  • Regular cleaning: Remove debris from the pump intake and impeller.
  • Impeller inspection: Check for wear and tear on the impeller.
  • Shaft inspection: Inspect the pump shaft for damage or corrosion.
