Compression Foam?

I have a few questions about compression foam used underneath larger tanks.
  1. How thick is the foam you usually put under your tanks?
  2. What type of foam do you usually use?
  3. The neoprene foam on this website seems like a good choice. What do you guys think?
My tank is a 21" tall tank (It's a standard sized 75 gallon). Assuming that the pressure ratings found at the link above is rated in psig (gage pressure) and not psia (absolute pressure), then the additional pressure due to a 21" water column above any foam placed underneath it would be ~0.87 psig. That means that the neoprene would not compress too much since it is rated for 3.5 + 1.5 psi and should help reduce stress points underneath the tank due to unevenness. I am thinking that one 1/4 thick piece should do the trick and the pricing is relatively reasonable. Any suggestions from you guys would be highly appreciated.

    Id just go up to lowes and grab some of the blue insulation foam. Cheap, easy, local, and works like a champ.

    I purchase the foam I use at Home Depot. It is about $12 a sheet for 3/4" thick and is pink; it's a 4' x 8' piece.

    When I took my 280g down last summer, the pink foam that had been there for six years was barely affected.

    I thought it was dangerous to place foam underneath to support the bottom of a glass tank. What am I missing here?

    Ask your tank manufacturer before proceeding. With my InterAmerican tank, I was told to use it. With the new Marineland tank, I was told not to.
