@Scott:
I'll update you on the noise issue, as soon as it is breaks in. At the moment, it's still too new and loud to say anything.
@reefkoi:
In the back corner? I wonder how well it would work then, because of the obstruction in the way of the flow. Would really kick butt, if it would work at the back. I don't understand though, why you can't use the old one that way, if it is stronger?
