For the tank I wanted it close to my drying room and heater as I want that to stay pretty warm. I attached a rough layout. I guess since my cabinets and everything are on that side too, maybe I should switch the tank to the other side.... Something to think about for sure.That is one big tank! But you can't really have too much water, just balance your weight
Have you considered bounding them as well with Sikaflex or the likes?
