Thanks all
Thanks for your comments,
Yes, I used PVC Cement to attach the rock to thin sheets of acrylic that I had cut to fit the tank. Basically, I took some of the live rock out of my tank and went at it with a hammer. I seperated the bigger chunks from the debris. I then glued the bigger chunks to the acrylic and let it sit for a while. I then filled in the gaps with PVC cement and sprinkled the rock debris onto the glue. After letting that site for a while I rinsed it off and put it in the tank.
I came up with this idea because of 4 main issues:
1) The obvious one is that I no longer have to scrub the glass (except the front) which is very difficult to do when I tank is built into the wall
2) I wanted my background to have a natural look. I had set up a 90 Gallon reef for my father a few years ago where we found a synthetic material to use as a backround and it looked nice so I wanted to find a way to do something similar....but natural is better.
3) I wanted to be able to attach zoas, GSP, xenia, etc to the background and have it spread all over.
4) I wanted all my critters to be able to crawl up my walls....they seem to love it.
