I just completed my weekend project of building a 2nd level for my male's 29 gal tank. I thought I would share how I did this and show how it came out as I have seen others ask about doing this. I just used styrofoam, bath tile grout, grout sealer and a hot glue gun to glue the legs on and the foliage. I texturized the pieces using a Dremel type hand tool so that the pieces would look more like rock and not just all flat and square. I am going to add a hide to the 2nd level, I'll probably get that made tonight or tomorrow LOL Well here are some pics:

Deebo came down his stairs twice and then decided to try the hard way LOL glad I added the vines cause he just walked right down them:
