Need advice on setting up 75g reef on tile in my Kitchen

[clownfool]

I am wanting to set up a 80g tank in my Kitchen on tile that is 1 foot square each. The person that laid the tile said I wouldn't be able to set up a aquarium on the tile because it would crack. What do you think?
the stand is 48" X 19". I am thinking that once the stand, aquarium, live rock,water, and canopy it would be very heavy, but I wouldn't think it would crack the tile.

anyone got a big tank on tile?

let me know

thanks
