Found this one.
Bit cheaper at $9.99.
Haven't found one on this side of the pond yet.
Think I'll stick with the Ehiem idea.
Still, happy to of been of help.
Now don't think that it has anything to do with overheating. my tank certainly has not overheated in the last week. Just not man enough for the job.
Have just complained to Hagen in fairly short manner. sent them a link to this thread and expressed my displeasure at having to replace my filter after only 9 months. Will keep you posted.
