I gotta ask this: On RC earlier today I made a post where I refered to a 150 gal that isn't being used. Well, I just spoke to my uncle like twenty minutes ago, and he asked to "borrow" it. He is looking to set up a fish only (no LR) system, and he says there is no need for a protien skimmer with it. There is a part of me that is screaming that this is just plain wrong, but he is a huge reason why I'm in the hobby in the first place. I'd like to give him the benifit of the doubt, and he has a couple beautiful freshwater systems, but can this work? Is the skimmer useful for primarilly(sp?), only Berlin systems like he says. Ugh, it seems wrong, but, well, family...
