120 gallon sump, 2 piece glass top

This is the sump that I'm going to assemble. I got it for a steal...$20 from Georgetown Feed Store. It had a broken drain plug, no big deal, I just ripped it out and the internal threads were fine. Had, "Russell Glass" in Gtown custom cut a two piece top of 1/4" glass that will keep dust and dirt out and also help control the temperature. That was $65. Not bad for 120 gallons!
