The aquarium rack I have been building with mostly scrap wood from Home Depot is nearly completed. I have to do some touch-up staining, bracket it to the wall for stability, and cover the surface with a layer of styrofoam so the variations in the wood do not damage the glass tank bottoms.
The styrofoam will also help with keeping the tanks level, something I struggled with a lot during construction. The wood was warped and twisted, and sometimes split. The rack is solid, built with 2×4 support for the weight all the way from the top to the floor.
The outlet below the shelf at the window has been replaced with a GFI so if I have a short involving the water I don’t electrocute myself. That just needs the cover attached and it’s done.
I hope to get this thing done over the weekend so I can start moving tanks into the room. It’s getting cold and I plan to heat the entire room rather than drop individual heaters into every tank. I lost some desert gobies last winter when a heater malfunctioned and poached them. I want to avoid that danger as much as possible.
