Aquavitro element Ca Calcium Reactor

Versatile, compact calcium reactor for up to 250 US gallons/950 liters

The element™ Ca Reactor provides and maintains a virtually constant calcium, magnesium, and alkalinity ratio, which is critical to the long-term success of reef aquaria. The element™ Ca Reactor functions by using CO2 to react with a calcium reactor media such as Seachem’s Reef Reactor™. CO2 acidifies the water flowing through the reactor and thereby dissolves the media which releases calcium, magnesium, carbonates among other elements and components of the chosen reactor media. A CO2 filled tank along with a pH probe and preferably a CO2 controlling system are required and/or highly recommended for proper functionality of the element™ Ca Reactor.


  • Easily Removable Inner Chamber
    The inner chamber can be removed without full breakdown making it easy to clean, change or top off media
  • CO2 Recycling Feature
    Make full use of CO2 injection by recirculating it using the element™ Ca's CO2 recycling feature. This also offers potential savings on the cost of CO2 canisters and refills
  • High Capacity Chamber
    The reactor chamber can hold up to 1.2 Liters of your choice of calcium reactor media (e.g. Seachem Reef Reactor™)
  • Effluent Control Valve
    Easily control the release of dissolved media into the aquarium. The water can be directed back into the sump, directly to the aquarium, or even a protein skimmer such as the aquavitro® division™ series
  • Highly Reactive Probe Placement
    Allows for rapid response by controllers to avoid over-shooting CO2 injection. Saves CO2 and allows for consistent and efficient dosing
  • Powerful External Pump
    Allows for higher column flow volume with more contact time and surface area. Allows for easy maintenance of the pump at any time

But wait...there's more

  • Easy Maintenance
    The element™ Ca can be quickly and easily dismantled for maintenance and thorough cleaning.
  • Anti-Vibration O-rings and Rubber Feet
    Additional sound-dampening features assist in silent skimmer operation
  • Setup Versatility
    The element™ Ca can be setup in three different configurations based on preference and placement within the system being run.
  • Patent Pending Compact Base Design
    Designed with a compact footprint in mind to fit in virtually any sump
  • Operation is Independent of Water Level in Sump
    Variations in sump water level don't impact the function of the skimmer
  • 3 year warranty
    The element™ Ca is guaranteed against defects of materials and workmanship for a period of 3 years from the date of purchase, except for the pump’s impeller. This can be extended to 5 years by registering your skimmer. The warranty covers the replacement of the defective parts.

Setup Versatility
The element™ Ca has the flexibility to be setup in three different configurations for managing the effluent and CO2 connections. This is a key highlight of the element's™ modularity and versatility.

Option 1 simply utilizes the connections as described in the instruction manual included with your element™ Ca Reactor.

Option 2 reverses these connections. Choosing between the two will be largely a personal preference, but factors to consider are how convenient CO2 regulation is setup for the system or where the effluent line might be better located. Additionally, in practice, some might find better management of CO2 recovery in one or the other.

If CO2 recovery is of primary concern, then Option 3 might be the better choice. Using this configuration, the effluent tubing connects directly to the base and no CO2 is lost. However, it is still beneficial to direct the effluent flow from the tubing into a protein skimmer such as the aquavitro® division™ series or to a point where there is consistent water surface disruption, ensuring that any possible CO2 is driven out of solution or that low pH water has its pH increased in value before flowing back to the aquarium
