Are you planning on gluing the rockwork together still or just the plugs for added support? I've had an idea close to yours, where I could run rods through my rockwork but only glue small sections together. So I could still remove parts for maintenance and what not easilySpeaking of rockwork, now that it looks like I won’t have to pack up the tanks for a move in the near future, I can go ahead with a project that I’d been planning. I’ve got a bunch of frag plugs both plastic and ceramic. My plan is to glue two together from the flat sides and carefully make holes in the rocks so that they’ll fit together kind of like 3D puzzle pieces. Here’s two samples I made. And on another completely unrelated note maybe it’ll sound a bit odd but the thing I’m most looking forward to is the snails I think.
