CalcFeeder Pro v3 

Manual for controller – and how it works:

The revolutionary and innovative calcium reactors, CalcFeeder Pro from Pacific Sun uses the latest generation of optical sensor to measure the amount of carbon dioxide in the column reactor. This ensures trouble-free operation as there is no need to use a pH probe and expensive aquarium computer/controller to measure the acidity of water.  The controller includes a speaker to inform the user about critical situations such as jammed main pump, empty CO2 bottle, etc.

The CalcFeeder reactor is a fully autonomous and independent system to maintain the right calcium / carbonate hardness (and other macronutrients) in salt water aquariums.

Adjusting the alkalinity level are as easy and increasing or decreasing the flow through the reactor using the touchscreen on the controller.

Using additional degassing column (model DC-1 / 2.5L volume or DC-2 / 7.5L volume) increases the efficiency of the reactor and raises the pH level in the reactor effluent.

The reactor can be supplied with any metering pump with adjustable flow rate (as included in the PRO kit) or with the bypass (from the main pump) or the gravity (the least recommended solution).

Each CalcFeeder Pro is equipped with:

  • Main unit – reactor CalcFeeder
  • A computer that controls an optical sensor in the column reactor – and thus dispensing carbon dioxide / solenoid valve
  • Built-in alarm indicating abnormal events – eg. the lack of CO2 in the bottle
  • solenoid valve with PE tubing
  • LCD touch controller with stepper motor dosing pump – designed for 24/7 continuous operation.

All CalcFeeders models could be used inside and outside sump.

CO2 control – how it’s made?

Pacific Sun is the first company to use optical sensors to control/measure carbon dioxide levels in the reaction chamber. By using the latest generation of optical sensor with four active photo-LEDs, this guarantees the precise dosing of CO2 and stable effluent parameters.

The special design of the reaction column ensures effective saturation of carbon dioxide in the water.

The CalcFeeder features excellent quality German pumps manufactured by AquaBee.

The CalcFeeder is made from the highest quality materials (100% pure acrylic) and uses silicone gaskets, guaranteeing easy operation for many years.

Calcfeeder body with optical sensor
Calcfeeder PRO controller with dosing pump (24/7)
