Yeah I definitely want a 300 minimum when I move into my house. I just don't like the thought of the glass breaking and having 300+ gallons of water flooding my place. I just feel safer with acrylic. I have a 120 and just the way it sits kind of makes me worry. I just thought this was a good topic and a good place to ask. If you can't have pleco's or an algae eater you just have to clean it I take it?
