I bet that would look awesome. you will have to let me know how that goes I wish I had more time to put into a big 100 gal + tank. Have you worked with clay befor? Iv tried the kitty litter clay background an it was not so successful. Looked great at first but slowly after a few months it just fell apart. So I'm trying great stuff. Now finding more then a hr a week an maybe I'll get some headway lol.
