This is not good, you deffinately want to have plywood then foam to support the WHOLE bottom pane so it doesn't crack.

Fwiw, the foam comes in pink, blue, or purple depending on brand. I have all three colors. As long as it is rigid styrofoam you're good.

This is what it looks like (these are small pieces):

Got the correct foam now thanks Myka. Grizz why do you say this? I had to replace a front pane of glass in a 125 and if I remember correctly the sides were sitting on the bottom pane. It was a while ago so I may be mistaken. I thought it would only need to be supported by the outside edge as with other tanks.

With the sides, front and back glass sitting on top of the bottom pane of glass there is way more chance of the tank cracking under the weight of the side glass. All it take is to get one corner a little higher then the rest and you have a stress point. make sure that the bottom of the tank is sitting perfectly flat EVERY WHERE. A properly built tank has all side on the outside of the bottom pane, its called a floating bottom.

i thinn the 180s are built like koles i just took off my broken piece of glass and found that it too sits on the bottom pane.. not sure why they did this with 180's but thats what caused me to make a measurment mistake of 1/2 inch.oops but i too will be doing plywood then foam then tank.
