otos...I saw those they look cool...but are they common?and how much would a 30 gallon filter cost compared to like a 20 gallon filter... 
I'm putting a 65 gallon and a 36 gallon in my son's bedroom. He currently has a 20g. A 30 gallon should be fine.Diego L. said:thanks ddayton21 I will do that...but I was wondering if I get like a 30 gallon do you think my bedroom floor will hold it?? it'll weigh like 300 pounds!
