Foam under tank?

[justinl]

You should be able to get neoprene foam cheap at a Home depot or something. Failing that, go to a camping supplies store. The cheap neoprene foam mats people use under sleeping bags is what I use. Same thing as what should be available at home depot but precut for sleeping bags, so that would be near useless for big tanks.

The company went for this but only because I did not have anything between the tank and stand. They told me flat out that would void the warranty. Just FYI.

very good point. I think it's stupid as what-have-you, but do take this into consideration.
