Description
In 1989, TUNZE® Aquarientechnik was the first manufacturer to develop a CO2-controlled calcium reactor. A circulation pump is used to pass the water enriched with carbon dioxide through the hardness granulate. The carbon dioxide reacts with water to form carbonic acid which dissolves the calcium carbonate, thus discharging softened water from the reactor. The new generation of calcium machines is comprised of two units:
The Calcium Automat 3171 is suitable for cabinet systems and aquariums up to 1,200 liters (317 US gal.)
All models are self-priming, which significantly facilitates their operational start. The water flow rate is adjusted prior to the granulate and will thus remain very consistent over time. All devices are equipped with a reabsorption function for the undissolved gases, and therefore consume very little CO2. The 3171 model uses a cover with a wide opening and contains a special connector for an internal pH probe.
