Vertex™ Rx-C 6D Calcium Reactor / Instruction Manual © Vertex Aquaristik ™GmbH, Deutschland 2014
Control:
There are different methods to Control and regulate operations of a Calcium Reactor. Vertex Aquaristik™
recommends the use of an Aquarium Controller or a PH controller. This will allow you to regulate and
monitor the amount of CO2 injected into your system through monitoring the PH in the main chamber.
The onboard Probe-Port on the primary chamber will allow you to place your PH probe in the primary
chamber. Ensure that the connection is properly tightened, do not pressurize the reactor as it can push
out the PH probe resulting in leaks, damage to property and your system’s inhabitants.
Depending to the type of media utilized and the reactor’s settings; the ideal effluent’s PH value could
vary from 6.3 to 7.2 PH.
Diagram 5 exhibits the relation between amount of gas injected, flow and PH value. However these
relations are not always linear and must be monitored and observed on each system individually.
Diagram 5
*Warning: A balanced relation and concentration between Calcium and Alkalinity is required and while
the points above apply, they are all affected if one value is reduced or increased. Explaining as how an
equilibrium can be reached is out of the scope of this document. Further to that concentration of other
ions such as Magnesium will affect the concentration of other said soluble ions such as Calcium and
Carbonate.
Starting your Reactor:
Now you are ready to start your reactor. To do so simply follow the steps below:
I- Chose the reactor’s location carefully. A calcium reactor requires periodical monitoring,
maintenance and media refill.
II- Ensure that all the O-Rings are properly seated.
III- Ensure that all the connections, unions, screws… are properly tightened.
IV- Ensure that your gas tank, regulator, solenoid, needle valve… is properly assembled, safe and
leak free.
