This has been in the make a while, but my new tank actually arrived yesterday, and this is how it's going to be installed: The floor wasn't very suitable so I decided to make a self-supporting shelf. The first holes. Supporting the galv steel studs while the concrete hardens. All in place (each stud can take 100kg static load). Wooden spacers to create more vertical room. Enough space for 3 circuit breakers, a timer, a LED driver and the neutral bar. Bottom cover fitted. Top and sides fitted Behind the cover The new tank is still on the dining room table, because there's still some work to be done around the shelf.
