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 revolutionary and innovative reactors calcium using the latest generation of optical sensors to measure the amount of carbon dioxide in the column reactor.
This ensures trouble-free operation (no need to use a pH probe and expensive aquarium computer/controller to measure the acidity of water).
Controller include external speaker which inform Customer about critical situations(jammed main pump, empty CO2 bottle etc)

The reactor CalcFeeder is fully autonomous and independent system to maintain proper level of calcium / carbonate hardness (and other macronutrients) in saltwater aquariums.

The reactor can be fed using any dosing pump with adjustable flow (as the one included in the kit PRO) or also using the bypass (from the main pump) or gravity (least recommended solution).
Includes sponge/foam pads for small size media.

Each reactor CalcFeeder 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 4m PE tubing

All CalcFeeders models could be used inside and outside sump.

CO2 control – how it’s made?
Pacific Sun is the first company which has used optical sensors to control/measure carbon dioxide levels in reaction chamber. Using latest generation optical sensors(with four active photo-LEDs) guarantee perfect and very precise CO2 dosing and stable effluent parameters.
The special design of the reaction column ensures proper saturation of carbon dioxide in the water.
As the main pump used excellent quality German pumps manufactured by AquaBee.

The entire reactor was made from the highest quality materials (100% pure acrylic) used silicone gaskets and closure of a “key hole” guarantees easy and friendly operation for many years.

Set include:
– Calcfeeder body with optical sensor
– Caclfeeder BASIC controller without feeding pump
– 1x Power supply
– 1x solenoid valve
– 2x holder for tubing
