placing a large stand on basement floor

[Chipie]

Hi,
I was planning to put a 180g tank in my basement and was wondering about the floor. It is what is called a floating floor(in french not sure how if it's the way it's called in english). It's a cement floor with what i think is strapping covered with plywood.

Will this be a problem? Should i put a very thick plywood under my stand ?

im running a sub floor ( i think thats what your saying) thats where floor beams are anchored to the cement and foam sheets are placed between joices, then plywood overtop, then your final flooring...

my final flooring is ceramic tiles where my 250 gal tank is, been holding water for a week and havent had any problem with cracked tiles or anything.. just make sure the weight is propely dispersed and not focused

It's only about 2 inches higher than the other part of the basement that is just cement. We bought this house and it was already like that so i don't know what's under

Anyone else have an opinion on this. My aluminum stand is built like a cube so the weight is distributed all around the base.

Should i put a thick plywood undeneath or will it be ok without on this sub floor.
