How do I make a 'fuge'

[MikeP]

I'm new at this and of course doing a lot of research. Through posts on this forum and reef central I think I would like to set up a fuge. I have a 30gal tank an aquaclear 300 and 15 pounds of LR (15 more will be bought over the weekend). I could make the AC 300 into a fuge or make a smaller fuge with the AC mini I have around here somewhere and just use carbon in the AC 300? or vice versa? Is this a good way to filter my tank? When I first decided to try salt I thought the filtering would be much the same as fresh with things like foam and bio balls, but it doesn't sound that way at all. I think I have the equiptment to filter this tank right I just need some direction on how to make it work.

Thanks for any help.
