VarioS CR140 5.5-inch Calcium Reactor: Successful Reefing Starts Here

High-Quality Calcium Reactor for Reef Systems

The VarioS CR140 DC Calcium Reactor is perfectly capable of meeting the challenging task of maintaining alkalinity, calcium, and trace elements in a demanding reef system. Quality, design, and controllability define the Reef Octopus VarioS Calcium Reactor series. Available in three different models, they feature the new VarioS variable speed pump and reverse flow water current reactor design to maximize water and CO2 contact time with the media. All models come with a pH probe holder (probe and pH controller sold separately) to monitor pH levels in the main reactor chamber and built-in bubble counters to monitor CO2 drip rates.

Calcium/Alkalinity Demand

  • Heavy: 120 gallons
  • Medium: 200 gallons
  • Light: 250 gallons

Key Features of the VarioS CR140 5.5-inch Calcium Reactor include:

  • Reverse flow and CO2 recirculating design
  • Auto fill bubble counter
  • Probe holder with plug* (does not include pH probe)
  • Easy to remove lid
  • Precision effluent control valve
  • Solid construction
  • 1/4" quick connect fittings
  • 2-year pump warranty

How the VarioS CR140 5.5-inch Calcium Reactor Works

A calcium reactor is essentially a chamber full of aragonite, which is the crushed skeleton of ancient hard corals. Aquarium water is pumped through this chamber along with pressurized carbon dioxide (CO2). The CO2 lowers the pH in the chamber to an acidic level, which dissolves aragonite media into the aquarium water. In addition to dissolving the calcium, this process also dissolves nearly all the minerals and trace elements the coral used in order to grow.

Automated calcium and alkalinity supplementation - when set up properly and used correctly, a calcium reactor can maintain or increase calcium levels with little to no maintenance.

What is a calcium reactor?

A calcium reactor is a device used in saltwater aquariums to automatically maintain calcium and alkalinity levels. It works by dissolving calcium carbonate media (usually aragonite) in a low pH environment created by injecting CO2. The resulting solution, rich in calcium and alkalinity, is then dosed into the aquarium.

Why use a calcium reactor?

  • Consistent levels: Maintains stable calcium and alkalinity levels crucial for coral growth.
  • Efficiency: Often more efficient than manual dosing methods.
  • Automation: Once set up, requires minimal maintenance.

How does a calcium reactor work?

  • Media dissolution: CO2 is injected into the reactor, lowering the pH and dissolving calcium carbonate media.
  • Effluent creation: The dissolved minerals create a concentrated solution.
  • Dosing: The effluent is dosed into the aquarium to supplement calcium and alkalinity.

How do i choose a calcium reactor?

  • Tank size: Consider the size of your aquarium and the calcium demands of your inhabitants.
  • Media type: Aragonite is the most common media, but other options exist.
  • CO2 source: A reliable CO2 source is essential for reactor operation.
  • Reactor design: Choose a reactor that fits your sump or equipment setup.

What's the maintenance required?

  • Media replacement: Regularly replace the calcium carbonate media as it dissolves.
  • CO2 adjustment: Monitor CO2 levels and adjust as needed.
  • pH monitoring: Check the pH inside the reactor to ensure optimal dissolution.
  • Cleaning: Regularly clean the reactor and components to prevent clogging.
