I read that knocking when stratup is common in the older koralias but the new evolutions and magnums have eliminated the problem.
I'd love vortech, really I would, but I don't have the necessary clearance for the dry side, unless I want to put the dry side on my viewing pane (which I don't). The tunzes look great too but the koralia's warranty is twice that of the tunzes and that's kind of a big deal for me. Not to mention the price difference.
This hydor controller looks cool for the price tag, just wondering is anyone had an opinion on it
