Agree with untamed. Use a high-density pink or blue colour piece of rigid foam insulation. Typically come in thickness from 0.5" to 3", with 0.5" being acceptable. Stay away from the white foam, it's not very dense.

foam
Actually it is the high density pink foam. It is the same I used under my 150 and it did compress there too. Not a great deal but some. On the new tank we are looking at about a 1/4 inch differnace from one side to the other. thinking the sheet is not consistant in density. Tank is 96 long

My 270 is full, no indentation at all in the polystyrene. And nice set-up BTW.
Is the tank level? Get yourself a 3' and a 6' level before you fill it with water. A lifetime of less then a level with a tank that size..........not good. And you do not want to do it after the fact. I would not expect there to be that much compaction with good material. If it is not level now, wait until you put water in it, then you will really see how it is out.
