I was able to finish the stand over the weekend to a point where I’m ready to put the tank on it and start plumbing. None of the stand is painted, but that will all be done prior to moving it into the house.
The plan is to setup the tank in the garage and leak test it prior to finishing everything else.
As you can see in the photos, the extra time spent doing the CAD work was well worth it. There is NO extra space between the shelf and the sump. I still need to figure out placement for the CO2 tank and the top-off water tank, but that can be done after the plumbing is figured out.
I had two friends come over and help lift the tank onto the stand. We probably could have done it with just two of us, but having a third person made things a little easier.
