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
The innovative Twin-Tech 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 built-in flow meter to accurately measure the volume of water passing into the reactor and uses that information to control the feed pump. This feature allows the user to know exactly how much reactor effluent, in liters, is being added to the aquarium within each 24-hour period, which is shown on a large LCD display in the center of the controller.
The water flow can be adjusted between 3 and 350 liters per day, simply by pressing two up and down buttons on the panel.
