V- Open the Calcium Reactor's Needle Valve fully and then turn on your metering pump. Supply
the reactor with Aquarium water, once filled reduce the flow-through rate to a minimum by
adjusting the needle valve.
VI- You must now turn on the Calcium Reactor's pump, this pump will stay on at all times.
Ensure that there is enough length of wire to have a drip-loop. When electrical devices are
operated in close proximity of water, drip-loops become more so important due to the
possibility of splashing, moisture creep... DO NOT IGNORE THIS WARNING! As always your
safety is our number one concern.
VII- Wait until the water inside the reactor clears and the reactor is free of air. Some small
amount of bubbles can be present. Do not be alarmed, in time this will subside.
VIII- Adjust the water flow exiting the reactor. The optimal Effluent flow rate depends to your
system's Calcium/ Alkalinity consumption. However for initial set up; we recommend to set
the valve to allow about 180ml/min or roughly 30 drops/min of flow. Do not flow too much
water through the reactor to start, this can raise the alkalinity in your aquarium and drop pH
too quickly which could be harmful to the inhabitants.
Caution: Always start at low output and allow a few days to bring the reactor to its maximum desired
output level. The recommended flow guidelines in this document should only be used as a marker.
Every system is different and without considering all the factors such as size, consumption levels... it
is impossible to make a proper assessment of what the optimal flow rate and CO2 Volume for your
system would be. Test your Effluent and Aquarium water frequently and adjust your system to reach
desired levels.
IX- Start the flow of Co2. Start with 30 bubbles per minute or less depending to flow rate, system
size and consumption.
X- Adjust your PH Controller to desired value depending to the media utilized and other involved
factors.
XI- Plug your CO2 Solenoid to your PH or Aquarium Controller.
Tip: Calibrate your PH Probe and controller at least once every 20 days. Refer to the manufacturer's
guidelines for optimal calibration regiment and use.
XII- Allow the reactor to run for a few hours, test Aquarium pH value to make sure it does not fall
below 8.
XIII- Adjust the flow and CO2 bubble-count to achieve the desired PH Value.
XIV- Measure the effluents Carbonate hardness after 6 hours of operation. This value could be
between 10 to 20 dKH. You must adjust this value to what is desired by your tank inhabitants.
XV- Measure your system's pH Value, Calcium and Alkalinity.
