This may sound stupid, but every time I silicone the plastic knob onto my tank lid, it doesn't stay long. I usually end up using a hunk of silicone as a knob, but it eventually has to be replaced too. I can't imagine that everyone has that problem. The lid is 2 pieces of glass with a hinge in the middle. Any suggestions? Fran
