Very nice looking tank! I wish I had those cabinet making skills too! Beautiful! Looks like you used the black pond foam over a PVC frame? How has that worked out? Looks like it's working and looking fine.
Thanks! I actually used the standard Great Stuff (red can) and painted it with Krylon Fusion. The paint is not as flexible as the foam so it is flaking a bit. It's all covering over with coralline and other growth though so no sweat. The frame from my last tank is still in use along the back wall of the new tank - it never received fusion or any other form of treatment and it's still in good shape.
