I had the backdrop for sale for quite some time, as it is an expensive one. I bought it for a 250L, but even though it's a beautiful backdrop, it also steals about 1/3 of the tanks volume, so I just don't think it's worth having in as small a tank as that. Nobody wanted to pay more than £50 for it so I decided to keep it and build the terrace tank instead - and no regrets there lol
It's not something you'd want to do with a new backdrop though..... I got terraces in two other tanks from it too though, so one day - when I get a house (if!

) - I'll have the two 250L standing next to eachother, and it will look as though the lower terrace continues i the other tank.
I'm sure it will work with a less expensive backdrop too though, one from AquaEl for instance. They're made of plastic, but look quite good! I only use them as backdrops in my tanks now, as they steal next to nothing of the colume, and they look good enough for me.
I know it sounds very extravagant to cut a backdrop like this in pieces, but.... it was just sitting there and nobody wanted it so... there you go...
I've seen bamboo used for making terraces, but I don't know how durable it would be in water. Maybe if it's coated with epoxy or something it would last? And that looks good too
Thanks for your comments, it always makes me happy when people say they like it, as I buildt it all by myself, and that I'm quite proud of LOL
