Hi, I've got an Oase BioPlus Thermo 100 filter and recently it has started making a weird buzzing noise. I did a water change and it was doing it even straight after the water change so I'm not really sure whats going on, it started happening recently and didn't happen before and I've not made any significant changes in the tank. Here's a video of the noise:
(it's only ~15s long, not sure why the vid is over a minute)
Anyone have any ideas on what it may be?
Thanks
