Few more updates on my build. I've been working on adding my water-change station to the office that shares the wall behind the display tank. I bought the modular units for home entertainment at ikea. We used these upstairs in the tv room and really liked them. I beefed up the cabinets a ton with plywood, metal brackets and 2x4s then mounted the entire thing to a few wall studs.
This shows the tank in the livingroom and the water-change station on the other side.
Looking into the office...
