I want to build a rock wall to encompass my glass tank. I cant keep a decent ambient temperature. I have watched videos and get the basic idea of what to do. You can youtube "reptile rock wall" and see some cool vids. The reason for my post is i keep hearing people say to use non toxic materials. I have asked for non-toxic stuff at Home Depot and at Lowes, i think the people who work there are retarded. One guy actually said "All this stuff is toxic if you eat it." What a moron! So, have any of you done this or do you know specific brands of products that would be safe for balls? below are the basic materials i will need.
non-sanded grout
grout sealer
cement dye
liquid nails
misc pieces of styrofoam that i will wash before i begin
