Foam under acrylic tanks

[swk]

Hey everyone. I was at home depot looking for rigid foam panels. They had 2 there, the regular pink foam board and a dense, white polystyrene. I would prefer to use the white cause my fish dig and I don't wanna look at pink inside the tank. Anyone use the white stuff before? I have generally seen either the blue, or pink board under peoples tanks so I figured I'd check first before using it.

Thanks

Easiest way is to cut foam to size and then spray paint it. That way you dont see the foam even in a bare bottom tank. Or just paint the bottom of the tank.
