I am thinking of buying a new tank when my girlfriend and I move into our first home. The problem is that I've found a plethora of tank manufacturers and I know very little about them. I was thinking of a glass tank any where from 125-210 gallon, with a closed loop. What are some company's to look into, and what are the ones to stay away from? I like the Elos look but the tanks are a little pricy is it worth it?
