Well I got started on the sump, but not alot done yet. I did with alot of help from Doug get my tank drilled for the drains and closed loop over the weekend. See I do make progress. Turns out that the front back and bottom of one of the ten gallon tanks was tempered, so shatter. I know now, when you make the cut with the glass cutter, before you try to pop the glass, listen to it. If it crackles...chunk it in file 13 cause its tempered. No crackle..pop away.
