spsboy, thanks for your input.
The tank is glass 115 Gallon(same as previous tank, but RR).
Stand has just been built and is pretty level and sturdy, I had screwed in 3/4 inch plywood on the top and could not counter sink the screws, it is very level with the board, but I was cautioned by Stevo to place the foam since the tank is not built with a frame around it.
Therefore, I thought I rather be safe than sorry, besides, too much effort went into all of this for tiny overlook like this.
