Im shopping around for houses and I really want an inwall tank with fish room but most of the single story houses in my area wont work with the floorplans available or there just too much money. I did find a 2 story house with a game room and a bedroom behind it that would be perfect for an inwall tank and fish room but its upstairs. Im figuring with a 200-300 gallon tank with sump, frag tank, hosp tank, refugium and other misc. equipment the floor would not have enough support. Has anyone done a larger tank upstairs? Any info would help and thanks for looking.
