Cleaning out my garage and used this as a holding tank for new fish. It's beat up but fully functional. The front side is a refugium and the rear has two chambers for filtration. roughly measures 24d x 30l x 20ish H. Also, have an aluminum 80/20 stand that's roughly 24d x 30l x 30+h. Sorry don't have exact measurements. If no one picks up by this weekend, it will get tossed. Makes a great QT tank
