I read that alot of the smaller tanks do not have tempered glass on the bottom. They are about $10 at wallmart, if you mess up it's only a $10 mistake. I'm sure someone here has done it and will chime in.
well here is the sump I after i finished it i was thinking that i may have built the skimmer section to small (which is on the left) so i was thinking about moving the skimmer to the center and putting the return pump on the left. The right side is going to be a refuguim.
