Aha, nice call. However I 'heard' that the thing might be vibrating through the cabling, so I'd need to shift it all around to the other end of the tank to allow the piping to run in and out without being in contact with the hood. But that'll have to wait as I'm going away for a few days now.
But many thanks for the tip, I'll try it when I get back to my tank.
Incidentally if anyone wants to buy the thing there's a thread and I'm open to offers. It works perfectly fine, I just don't think it suits my particular tank.
