Does the same colour carpet run the length of that floor? I am not a big fan of that colour but yes they do sell those plastic carpet overlay for construction with adhesion on one side, I think movers may use that too...mind you it works better on low turf carpets like the ones in the office but should be ok for this application. I am not too sure if you're a careful guy with tanks or clumsy like me, every tank I've owned has had spills some big some small, ato bins have overflowed one too many times, I should already invest in a float valve. Anyhow everything else looks like you're off to a good start. I didn't see any windows, will you be adding a dehumidifier or something as it could get very moist having that much water in one room.

Are the two tanks going to have independent sumps?
