Live rock, won't create the effect I'm looking for (3 sided rock pool, hidden equipment), and I don't have a kiln for ceramics, the other options are concrete (but 2 months to cure, thinking of a nano tank for the competition), or as a friend of mine suggested real rock and an angle grinder:lol:.

Yes, i'm looking at creating a 3d background with ledges, caves etc, on three sides of the tank, the effect I'm thinking of is a rock pool with window.

I'm sure I can remember seeing it somewhere being used in reef tanks, although I'm not too sure, that stuff really stinks when you burn it.

Like Mekaeel said, you can buy the ready made backgrounds, but they are rather expensive.

I've tried polystyrene in my snake tank and expanding foam in the frog tank.

You can see the polystyrene in the background. I melted it with thinners and then a slurry mix and paint. Worked quite well

This is the expanding foam from Braeven. Got it at Builders Warehouse. I phoned the manufacturers to see if it was safe but they didn't know so took a chance. I do know that polyurethane is safe once cured but really dont know how safe it would be in an aquarium
