I have an 8 gallon bio-cube. http://www.oceanicsystems.com/products/biocube.php#
I unplugged the filter because i was emptying the tank to add sand. (there was nothing living in the tank)
I then re-plugged it back in... a few days later.. and now there is this very load noise... sounds like a motor
i tried turning it on and off (unplugging and re-plugging)
still very load disruptive noise
any ideas on how to fix it?
