Hi, I'm new to this forum but have been reading it voraciously for all the great info. We're getting an octo and want to escape proof the tank? As i've been reading through the posts i've noticed the mention of both duct tape and acrylic glue? used to adhere netting and the like. Is duct tape safe to use in the saltwater? It won't leach any chemicals? and which glue? thanks so much..
