The Koralia Nano 550 is a new propeller pump from Hydor which joins a growing field of new water movers in this small pump size class. Rated for 550 gallons per hour, the Koralia Nano 550 is the same size as the previous Koralia Nano 425, but with more windings providing the oomph to push the flowrate up by 30%.
Hydor’s new Koralia Nano 550 uses only 5.5 watts and it is suitable for tanks between 35 to 45 gallons, and the flowrate we witnessed coming from it is probably going to push a nice mild flow for up to two feet of reef tank with moderate flow corals. Like previous Koralia Nano pumps, the Koralia Nano 550 has a simple magnetic-suction cup base mount with a basic ball joint for articulating the pump up to 60 degrees in all directions.
