Check the watts on the bulbs to see if they are NO (normal output) or HO (high output). 36" T5HO bulbs will be 39 watts, 48" T5HO bulbs will be 54 watts, and 72" T5HO bulbs will be 80 watts. What are the dimensions of your tank?
If your tank has a plastic frame on the bottom that holds the bottom pane of glass off the stand then you don't need to use the sytrofoam. Styrofoam is recommended for tanks with no trim though. However, provided you use suitable styrofoam, it does no harm to use it even if your tank has trim. I use it under all my tanks - trimmed or trimless. Buy the right stuff though, it has to be dense styrofoam, not the type where you can see the little balls of styrofoam melted together.
