Hydor is set to release two new Koralia Nano versions of its redesigned Evolution series shortly giving nano reefers reason to rejoice. A small footprint at only 2 1/2 inches each and available in a 240 GPH and 425 GPH version, these tiny pumps will give you plenty of circulation no matter the size of your nano with all the benefits of the new Koralia Evolution pumps. Like the other Koralia Evo pumps, the nano version feature a shaft-less propeller allowing easy switching on any wavemaker or timer and low power consumption of a mere 3.5 Watts. No word on pricing or availability yet but if the performance is on par with the larger versions of the Koralia Evo pumps, these are sure to be a hit with nano hobbyists. We’ll be sure to post availability and pricing as soon as we hear it.
