DIY Aquarium Decorations?

[SixFootDaisy]

Anyone have any ideas on what to use?

Paint, materials?

I want to make some things for my tank, even though I have the egyptian theme, but I do still have an empty 10g...

plaster of paris.

I think you have to soak it once its cured for a few days

I heard of someone making their own castle out of plaster and gravel.

I know guys that have made plywood marine tanks and sealed them with pool paint. I'm also interested in knowing what kind of paints can be used as I'll be painting the inside of my stand and canopy.
