Anybody have any large tanks in thier upstairs?

[rudy]

I am going to have a 8x36 x24 tank built against an outside wall on the main floor of my house. Orginal design was 10x 36 but due to wall size that is not going to work so I have had to scale off a couple feet of length

My question is I have a 1970s home in Silver Springs with 2x4 diagonal joists in the floor. I am obvisously worried about the weight. My current tank there is 220 gallons and is 6 feet but with the sump and size of this tank what am I going to need to do to reinforce the floor properly.

Does anybody know anyone in Calgary who can give me an honest opinion.
