Introduction
Congratulations on your purchase of a Deltec Twin-Tech Calcium Reactor, described by Reefbuilders as
the “Supercar of Calcium Reactors”
These instructions will guide you through the installation and running of your new reactor with tips and
advice for getting the most from your unit

Principle
This latest generation reactor operates on the principle of total CO2 saturation by the continuous
recirculating of the water in the reactor through a large bubble of gas.
The CO2 dissolves in the water until it is fully saturated, which occurs at a very low pH, at which point no
further gas can be dissolved until additional water is added to the reactor.
The whole process is controlled automatically by the digital controller and float switch in the gas chamber.
As the CO2 bubble dissolves in the water, the water level rises, which raises the float switch and triggers the
solenoid valve to add more gas to replenish the bubble.
Features
This innovative reactor has several unique features providing simplicity of control but also relating to the
way that the system feeds the reactor with water from the aquarium.
The smart controller on the Twin-Tech uses a flow meter to accurately measure the volume of water passing
into the reactor, it uses this information to control a standard DC feed pump.
This feature allows the user to know exactly how much reactor effluent, in litres, is being added to the
aquarium within each 24-hour period, which is shown on a large LCD display in the centre of the controller.
The water flow can be adjusted by the user between 10 and 350lt per day simply by pressing two up and
down buttons on the panel.
Contents

1 – Large media chamber.
2 – Smaller gassing chamber with float switch.
3 – Controller with separate power supply unit.
4 – Recirculation pump and connections.
5 – Feed pump with suction filter.
6 – Low voltage solenoid valve.
7 – Hoses and non-return valves to connect the unit.
Not included
1 – CO2 bottle, CO2 regulator (important, 2 stage regulator is required) and CO2 hose.
2 – Calcium reactor media.
