Thanks. I tend to be a pack rat with fish stuff. A couple years ago, tat2shawn and I redid my basement portion and built nice sturdy stand I have now. Prior to that, the tanks were on shaky 2x3 stands that a sneeze might have knocked over. When we redid everything, I worked tanks that I had sitting around dry into my system and the "manifold" off my drains makes it more of a glorified sump than multiple tanks. This way, too, I can run it all on just one return pump. Each drain has a reverse durso on it to minimize the bubbles in the tanks.
