finally dropped my filter off at a friends house in c-bus for him to hopefully fix it. He showed me some pics of the tank in DC he services every week. The main tank is 20ft x 12 ft by 5ft & has a few sharks & some other cool stuff. Hopefully he will email me some pics of the tank soon so you all can see what it looks like, really cool tank!! It's made of 2in acrylic & was made on site obviously. The moron who designed the tank only left a single 2 or so ft square opening on the top, only one!! The designer of all the aquariums/filters is a complete moron..... he contracted aquart to make the tanks & is over maintenance of the house.
