New version of CalcFeeders with ultra silent step motor feeding pumps and smaller footprint!

V3 version was built for customers who have limited sump space – one column and smaller footprint. This version of calcium reactor is two-in-one: mixing chamber and also media chamber.

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.

A revolutionary and innovative calcium reactor that uses the latest generation of optical sensor 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 includes speaker to inform the user about critical situations (jammed main pump, empty CO₂ bottle etc)

How it works?
When your alkalinity in aquarium drop – you need to increase flow thru reactor(on touchscreen of controller) . When your alkalinity is too high – you need to set smaller flow on controller. That’s all! It’s very easy to understand by beginners but also advanced aquarists.
Device regulate automatically proper amount of carbon dioxide which need to be dissolved in water and keep pH in reactor on proper level which allow to dissolve media inside calcium reactor.

The CalcFeeder is a fully autonomous and independent system that maintains ideal levels of calcium / carbonate hardness (and other macronutrients) in saltwater aquariums.

The CalcFeeder can be fed in a number of ways however the Pro Version includes an inbuilt dosing pump. Other ways to feed would be the use of any dosing pump with adjustable flow, or using the bypass (from the main pump) or gravity fed (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 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.
