Hi everyone, I'm working on my first serious display tank and need some advice. I have already siliconed a mat of epiweb to the back, and I have a large piece of driftwood that I want to attach to the epiweb. It is a fairly large piece (and absofrikkinlutely amazing, credit will be posted when I am finished the tank!) weighing 10-15lbs. I will be putting in supports on the base so it is not completely hanging onto the background. My question is, what is the best way to attach the wood to the epiweb? Silicone? Greatstuff? Any other suggestions?
