I appreciate knowing that too. After looking around, it appears that koralia is very bad about doing this. Maybe taking it apart and cleaning the rotor/impeller will help it. There should be some kind of "mechanism" that prevents it from starting backwards.DOWNSTAIRS display tanks:

its prolly more to do with the electrical design that something mechanical, if i had to guess. i'm not experienced with these pumps though but when motors run backwards its beacuse something in their design is allowing the motor to run out of phase. i guess that would be easy to do with an induction motor design.75G Standard - High Light Planted Community Fish

It's a single phase reluctance motor I believe, so it will run either way. They usually do something in the design to make it go the right direction at start-up. Apparently, these koralia motors have some kind of bushing that gets out of place. They make some kind of replacement parts kit with a bushing that won't slip out of place.DOWNSTAIRS display tanks:
