do you guys think there will be drastic amount of difference in noise from Bean's setup compared to the glass holes? has anyone setup the glass holes kit? i really liked it because it incorporated a durso into a very small unit, and the overall size of the box itself is small, so for like a smaller tank like mine its good..Bean's setup is definitely better, as far as safety features and quietness, but just not sure...thanks for all the inputs, greatly appreciated..
