Note: Those who do not clean the Heizstaab previously thoroughly under running water, loses its complete inventory !!! If you read in other reviews !!
My buddy was too lazy and a day later was received by it all down to the last fish ... did the same, only made clean work but as I said with high variations. Get yourself one of Eheim, then is good. Has no value that thing. For emergencies I have now abolished it once.
