Instructions for use


Calcium Automat 3172

Calcium Automat

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 quariums up to 1,200 liters with a granulate capacity of 1.85 liters.

The Calcium Automat 3172 for cabinet systems and aquariums with 2,000 liters and more (depending on the coral population) has a granulate capacity of 10 liters and an especially high degree of efficiency.

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 models 3171 and 3172 use a cover with a wide opening, and contain a special connector for an internal pH probe.

The heart of the Calcium Automat is a special calcium pump with a blending centrifuge, for a particularly high degree of efficiency and CO2 mixing.
