Melev- I've seen tanks that use a lighter thickness on the bottom (or end panels). Especially the large tanks. It does depend on the depth of the tank, and the span. While the bottom of the tank is fully supported, the sides are not. Picture what happens if you glue only the front to the bottom, then pull outwards on the front. The bottom will flex, until it, or the joint, breaks. That is the same type of forces being applied in the tank, so you don't want to go ultra-thin on the bottom.

For a 30x20x20, I think you might be OK.
