The Classic CR624 GEN 3 will hold 16 pounds of large grain media and is a reactor well suited for large SPS reef aquariums from 200 to 300 gallons.
What’s New with the Generation 3
The Classic Generation 3 Calcium reactors are very efficient and quiet and are designed to run similar to their Classic GEN2 predecessors. The main difference is a significant decrease in power consumption from the recirculation pump (23 watts down to 9 watts), decrease in pump sound (70 %), auto purge of air in pump since pointing upward, a decrease in Co2 chopping sound at injection and all hard PVC plumbing.
About the Recirculating Pump
Do not underestimate this extremely energy efficient smart pump based on its size and low replacement cost. During operation it is slightly warm to the touch, super silent and has over a 3.5 year continuous run rating. Some of its smart features include “Debris Jam Protection” stoping the impeller from being damaged and “Dry Run Protection” to keep the pump from over heating if there is no water in its housing. The materials in constructing this pump are designed for alkaline environments and are resistant to salt corrosion making this pump well suited for the extreme water conditions of a calcium reactor. The low gallons per hour on this smart pump is intentionally programed for two reasons: 1. low vibration sound and 2. to actually allow sediment to accumulate on the bottom of the main chamber so not to be pulled back through the closed loop of the reactor damaging the pump impeller and possibly clogging the effluent tube line. Thousands of hours of real world experience led to choosing this smart and efficient pump.
