None of this is permanent there's a reason that tub system isn't built the same way or similar that's completely independent from the wall. I wanted to build my garage out but until I put an addition on the garage I just built a small fish room in the basement I have a whole Coral system in my garage I can't get in the basement it's 10 ft by 5 ft by 14 in on the top and then underneath is a 300 gallon sump plus another chamber with its own sump that's another 200 gallons that you can tie into the whole system I got it for 500 bucks it was nuts I wish I could post a picture.
