K2R Calcium Reactor

The R2K calcium reactor offers a simple solution for calcium and alkalinity maintenance of reef tanks. It is especially well suited for stony coral type tanks where calcium and alkalinity demands are high. The K2R uses CO2 gas injection to lower the pH of the recirculating water to a point where the aragonite contained within it is dissolved. This helps maintain both calcium and alkalinity. You will not need to drip kalkwasser or add calcium chloride solutions to maintain the essential element of calcium in your reef tank. K2R features all acrylic construction, reliable Eheim pump, and integrated bubble counter. 1-year warranty from date of purchase on materials and workmanship. Height: 19-1/2" Footprint: 8" x 8" Capacity: Up to 450 gallon tank * Calcium reactors require substrate and a CO2 system and pH controller to achieve ideal water chemistry.
