Hydor Koralia 4 acting crazy :)

[Whynot91]

I have been using this Koralia for less than year, been working great. I got a new tank and put it in there. I should have probably waited till the sand settled but I'm pretty impatient. I dunno if that is what is causing the issue.

Anyway, when i turn on the Koralia now it stops after running for 1 second. When i take out the impeller there are small magnet pieces. I clear them out, run it again and it does the same thing. I dunno where they are coming out from. Almost seems like its grinding. The impeller however is ok, so i know its not from there.

Any helps/hints? Also. If it is grinding what part exactly would i need to replace?

It sounds internal, which means you might have to buy another unit.

Yes it is. I had the same problem with a fish spitting sand into the thing. Take it out and let it dry off. Get a cotton swab and clean out the impeller well until there is nothing left in there. Clean the magnet of any chunks or pieces of sand that are ground into it. This should do the trick, if not you may just need a new impeller.
