In the next week or so I will be setting up a 39 gallon CAD signiture series and was wondering if anyone had any advice on how to set up the overflow and refugium chambers. I bought the system used, I believe it is the 2008 model, with the silver light fixture. It came with bio balls for the overflow, but I'm not sure whether to stick with those, use rock rubble, or use some combo of other things. I've never had a refugium before, so I'm not sure what works well. Any advice any of you have would be greatly appreciated. Thanks.
