Thanks everyone!
Kris, I almost felt like an addict giving an introduction!
Grassi, I spent a few months on NR before finding this site. While there was good information at times, I had a hard time with all the flaming that occurs when people asked simple questions while learning. Sometimes forums can be a little rough.
It took me months just to settle on a tank. I was researching like crazy and I spent countless hours on the computer confused as ever. My wife finally got to the point of saying "just choose one so I can have you back"
