Ryan,
Yes, the algae area I am referring to is a refugium. I hesitated to call it that only because in a lot of my reading it is not really *technically* a *refugium*?....but yes. I made it myself, and modelled it after a few HOB types I've seen.
I have the output on my Seaclone going into the fuge, through a series of baffles, and then draining right into the main tank. It's set a few inches above the level of my main tank. I've got some LR in it, chaeto, some other types of algae and a DSB. The total volume this fuge holds is about 4gal......it's 12"x4"x20" in size.
I dont think that's an ideal size for a 40g tank though is it? That's why I kept the cannister....

So taking out all of the media in my cannister and replacing it with LR would work just as well??? (except for the simple form of mechanical you suggested) I'm assuming you mean the charcoal as well? OMG if so it's done tomorrow! It seems to make total sense though when ya think about it!

Thanks tons Ryan!
