Marine Calcium Reactor

Maintaining calcium and alkalinity levels in your reef aquaria
 

Kalkreaktor KR 400

A reactor to supply dissolved calcium and calcium bicarbonate ions to reef aquaria up to

The Calciumreactor KR 400 is a sealed system operating at a very low flow rate. Within the reactor calcium and calcium bicarbonate ions are release by the controlled dosing of CO2 gas. This provides the calcium hydrocarbonate that hard corals require to build their exoskeletons. The filter can be installed in almost any position, inside or outside the aquarium or the cabinet.

To provide the water flow, we recommend our SP 1500 dosing pump. The reactor is filled with Hydrocarbonate – a pure form of calcium carbonate with an extremely low phosphate level. For optimum control and the most economic use of the CO2 gas, we recommend the reactor be used in conjunction with a pH controller or pH computer. The reactor is already equipped to accept our specific pressurised electrode.

Dimensions - without electrode (l x w x h): 14.4 x 10 x 37 cm (c. 5.8”x 4” x 14.5”)

Hydrocarbonate
art.no.: 410.30
 

Kalkreactor KR 1000

For the supply of dissolved calcium to reef aquaria up to 1000 litres (c. 250 gallons)

The Calcium Reactor is a closed system designed for universal use. It can be operated on a bypass system, independent of the water level in the aquarium, or alternatively be installed in the filter sump. It includes a large volume (10 litres or c. 2.5 gallons) of Hydrocarbonate and an integrated circulation pump that features the patented Aqua Medic needle wheel.

 

By adding CO2, the pH value in the Calcium Reactor falls and the Hydrocarbonate is dissolved. Even with a low flow rate of 1 to 4 l/hr (c. 0,25 to 1 gph), a large amount of dissolved calcium enters into the aquarium, which is assimilated by the animals. The Calcium Reactor has an integral port to accommodate a PG 13.5 threaded electrode to measure the pH value and an SP 3000 dosing pump for controlled water flow.

Calcium Reactor Tips and Tricks

  • It is strongly recommended that you use a pH Computer or Controller with a High Pressure pH Probe to manage the pH inside the reactor.
  • Replace your media every two years, or when it seems to be half gone. This avoids compaction, flow restriction and anoxic conditions within the reactor.
  • Check the water and CO2 flow rates regularly for deviations.
  • "While using a Calcium Reactor it is more important than ever to regularly maintain any submersible pumps within your system including the Calcium Reactor circulation pump . Cleaning the magnets and impellor pockets of mineral deposits, which are accelerated by a Calcium Reactor, becomes essential for these pumps to achieve a long life and to maintain optimal performance."
  • "Use a Kalkwasser Stirrer in conjunction with your Calcium Reactor, as a part of your automated top-off system, to achieve outstanding calcium and alkalinity levels in even the most demanding SPS displays."
  • Always use Aqua Medic Hydrocarbonate media in to ensure the finest quality effluent from your Calcium Reactor
