blue sheeting?

[eederise]

so what's the blue sheets of rubber-like material that I see some of the folks here placing under their tanks and sumps? Where can I get some?

[JetCat USA]

it only goes under acrylic tanks/sumps and you can get it at most any building supply, it's made by Georgia Pacific.

It is blue Styrofoam... As JetCat mentioned it is a GP product. You can get it at HD or LOWES. They may also have pink or yellow compressed foam sheets that will work as well.

As jet also mentioned, it is not needed under glass tanks (it can actually cause more harm than good.
