News about the Tunze. If you mod the first chamber with a second water return, I can't see the Tunze fitting in that chamber. I am almost ready to put water, sand, and rock in my tank and I am just finishing up mod's to do so and there is no room left to add an in chamber skimmer. Even if I wanted to do the FIsson (I've read that it is a peice of crap), there wouldn't be enough room to fit it. It's just too tight back there.
Remoa Nano, here I come.
Good luck
