The new Geo’s Reef CR510 nano calcium reactor is only nano in the sense that it is smaller than other Geo’s reef reactors, but it is still able to hold 5 lbs of calcium reactor media and should work for systems up to 120 gallons. What is interesting about this particular Geo’s reef calcium reactor is that the standard bubble plate is replaced by a diffusion injection system allowing the whole reactor from the bottom to be filled with media, with no wasted space like seen when a bubble plate is used. Certainly and interesting take on the flow design, but only time will tell if it actually works well.
The Geo’s reef CR510 calcium reactor is powered by a MaxiJet 1200 and otherwise offers a standard design with a keyhole for pH probe, and thumb screws that keep the removable lid in place. These new Geo’s reef calcium reactors will be available in the next couple of days, and will retail for 250 bucks. When released they should be available for purchase on the Geo’s reef website, under the Calcium Reactor product category.
