When you think about it, us MFK'rs are the minority when it comes to so called "monster tanks." Even the folks on here with 1,000 to 100,000 gallon tanks are like in the 99th percentile. I remember when I had a 120 gallon in college (still have that tank running in my dining room), everyone who saw the tank said that it was just ridiculously huge.
Face it, the number of folks with 100 gallons or more in there homes are probably few relative to those who may not have tanks or have tanks up to 100 gallons. That being said, I voted 200 gallons. My estimation is that those individuals with 200 + gallon tanks are few and far in between...relative to the rest of the world that is.
