Looks like it would be easier to just cut one of the big roots in half and silicone it to the wall

No kidding. You have to break it apart to get it in the tank anyway. I see he likes to work in the middle of his living room too. :)

That looks REALLY cool! The cool thing about the roots idea is you can scale it down to fit any size tank.

I like this idea. Its an unusual background, and he used the perfect colour. Here in Germany you can buy mangrove wood and roots for tank decoration, and I know the color.

Inetresting will be which kind of color he will use BETWEEn those roots.

I think its not too much work to cut away the spaces between, all you need is a real sharp carpet knife. And I would use somewhat thicker styrofoame. But thats just a matter of taste.

Looks like quite a project. I'm glad I didn't pick that size for my first one :)

Looks great, but the idea of styrofoam in the aquarium just sounds dangerous to me

Styrofoam isnt dangerous, as long you use the correct colors and finish.

What I dont like with styrofoam is its habit to float, or at least its trying to float. When you use this stuff one practically ruins his/her back of a tank, cause one needs loads of silicone to keep that stuff where it shall stay.

Ever tried to scratch away silicone??? aaagh

Very true, the styrofoam itself is just about as toxic as a filter sponge :)

Silicone can be removed with with a few tricks. First cut away what you can using a razor blade. Then rub the rest off with talcum powder, before finally cleaning off any stains with isopropanol. It takes a bit of work, but it is doable. Some commercial products are also available to make this easier, but you need to be carefull so you don't damage the silicone holding your tank together.

I prefer to use non-toxic heat activated glue instead of silicone. Makes it harder to cut the background out from the tank, but the glue itself is much easier to remove. You also need less of it, and I love the fact that it hardens within a few minutes xD

If you are paranoid you can use silicone around the edges, to seal off the glue. Of course you must then wait for the silicone to dry.

(yay, my 300th post, and in only two weeks *laugh*)

Crack, the Styrofoam is covered in a quick set cement and allowed to either cure or sealed with epoxy. I would think this might be hard to hold in place, however. I would have liked to have seen some finished pictures.

An electric knife probably would work fairly well at cutting this stuff like that.

That would take me 50 years to do, atleast!
