I've had my Eheim 2126 (external canister wet/dry thermofilter) for about 7 months now, and it's been silent.
But, over the past couple of days, it's started making an annoying sort of "rasping" sound, like a light buzzing, but only when it's taking water IN. When it's pumping water back out, it's fine.
Anyone any ideas?
