Hydor Koralia Nano Evolution Circulation Pump
Free Gift


Compact, energy saving, this Hydor Koralia Nano Evolution Circulation Pump is ideal to recreate in aquarium the natural and beneficial water motion of rivers and seas. Supplied with patented magnet-suction cup support for easy and safe positioning, Koralia can be connected to a controller and set to intervals of seconds, minutes or hours. Cable protector include (read instructions for correct positioning).

Are the Koralia Nanos safe for use on wavemakers?

Yes. Like the Koralia Evolutions and Magnums, the Koralia Nano 240 and 425 are designed to handle operation on wavemakers and timers.

Is it normal to hear a click when the Koralia Evolution starts-up?

Yes. You may hear a slight clicking sound when the Koralia Evolution starts-up. This is caused by the impeller resetting itself by hitting the rubber bumper on the inside of the front cover. Removal of the bumper will prevent this noise but, without the bumper the Koralia Evolution can run in reverse.
