hi Dylan - i now use that dense flexible foam that comes as camping bed rolls - got black under the new tank way smarter than white polystyrene, doesn't crumble either, and takes the pressure way better.

Wooden flooring underlay......very thin, designed to take weight and doesnt crumble or absorb water.

1" polystyrene covered the entire base of the tank.

MacSalvors carry them in stock if you need any.

I was told by a guy who makes tanks that the thinner the better as long as the polystyrene takes up any uneven areas in the base the tank is sitting on .
