refugium set up for small reef tank

[Jin]

I have a 20 gal. reef tank that i am adding a refuguim to. I don't quite know how i want to plumb it. I've heard people say that above tank sets ups are better and next to tank set ups are good too. I currently am thinking of a beside tank set up. I am recently new to the hobby and am looking for advice on how to set up the plumbing and position of the refugium. I made the refgium from a ten gal. tank. it has a glass box on the right for the inlet pipe and three glass baffles on the left for bubble control as well as a compartment past them for the return pump and bio balls. any advice and experience on this would be much appreciated, thanks

CPR makes on that is a hang on for the tank. There's a large and small, only $10 difference but you may want to check the size.
