TUNZE Calcium Automat 3172
The Calcium Automat 3172 for cabinet systems and aquariums with 2,000 liters (528 USgal.) and more (depending on the coral population) has a granulate capacity of 10 liters (2.6 USgal.) 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.
