Calcium reactor PF-series

In the seawater aquarium, the pH value should be on average at 8.2 and in the calcium reactor at about 6.5 or less. The lower the pH value in the reactor, the more effective it works.
The filling material, e.g. calcium granulate, is dissolved with a mixture of water with the addition of CO². To make this process possible, acidic water is required.
We recommend “HY Carb” or “Hy Carb Special” from our Aqua Crown brand as filling material for the calcium reactor. In addition to calcium, “Hy Carb Special” also contains magnesium and therefore does not have to be added separately.

Basically, the calcium reactor is controlled by the amount of CO² supplied. I can see the amount of CO² added in the bubble counter. Depending on the device type, a certain number of bubbles per second must be visible in the bubble counter. Please refer to the respective operating instructions for these values. For the exact setting of the pH value, a measuring electrode can also be connected to. Thanks to the Deltec fluidized bed process, the medium is optimally mixed with the water. Compared to conventional calcium reactors, this results in a much higher degree of efficiency.

For a healthy development of the corals, the calcium value should be around 450 mg / l and the carbonate hardness between 6 and 8 degrees.

When generating or enriching the aquarium water with Calcium, so-called process or false gases are created. These are harmless and are automatically discharged from the device via the return flow.

Basically, this depends on the size of the aquarium, the number of fish, living stones and corals as well as the type and duration of the lighting. We recommend around 200 litres of aquarium water per liter of lime water reactor with a normal population.
