Hydor

The new Hydor KORALIA Magnum models 5, 6, 7 and 8 guarantee unbelievable performance for probably the lowest power consumption of any pump on the market. Equipped with an electronic start up system, new technologic rotors and propeller, compact in size, these new models will quickly become leaders in their flow categories (6.500, 8.500, 10.500, 12.500 l/hr). KORALIA MAGNUMs have a pleasant design and come with a powerful magnet-suction cup support that rotates to direct water flow easily. KORALIAs can be positioned safely glass, anywhere in the aquarium.

Why is my Koralia Magnum impeller not spinning?

The Koralia Magnum impeller rides on 2 bushings. If the bushings are stuck to the magnetic shaft, then the impeller will not spin. Unplug the unit and remove the impeller to clean the bushings. One is located near the top on the impeller and is hidden by the black wing. The second contacts the bottom of the magnet. Once the bushings are clean, reinstall everything and plugg the unit back in.
