After being told that I might be a little shy on filtration for my new tank, and being on a strict budget, I went out and purchased this little guy. I hope it is enough. What do you guys think? I also have an aquatech 60 hang on filter running as well on this 75 gallon tank.

A Rena? That's what we use. We have two of them, 4 layer canisters and a Diatom. I think they work great but now hubby is talking about making his own using a utility pump and filter pumps like you use in your house. Sigh, men.
