large tank on main floor ? anyone help

[banditpowdercoat]

I have a 150g tank with 70g sump in a Mobile Home. No extra bracing, no issues. If you put tank across the joist's, and close to a load bearing wall, you will have no issues either.

One more thing i forgot to add is that my contractor told me my joint bent a little when he measure it with his level.
