Hello!
I tried to find information about this online and in english forums, but i find most forums speaking about dennerle is in german, so i hope there is someone here with the 30L marinus or 60L marinus to help me.
Including in this package is the Bio circulator 4in1. I have a bad noise coming from mine, Its not from the engine or the scimmer. If i have the engine separate in the tank, its just a normal engine sound (very low). If i have everything connected i get a bad sound, the sound is also there if i take out the "scimmer". I have attached a video file of the noise. If any of you guys have this Circulator and have the same noise or can help me out i would be happy. Because i think this noise should not be there?
Best regards.
Here is a video of the sound (clicking) https://www.youtube.com/watch?v=TujUb1AZ81E
