Hello,

At my school we have a project called zeehond ( = seal ), the point is to keep salt water fish that lives in the North see especially the Belgian and French coast. So now we are bussy setting up a new aquarium, and because this will become our main aquarium to display our fish we want to make a nice background in it, but we have no idea what kind of material we need to use.
Is there anyone who has some experiences with this ? Every suggestion is welcome, I have a 2 week deadline...
