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 anytime.

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
