Thought I'd start a log for my new build. "Reef ready" 60-gallon cube. Made an escape proof lid with a 23 1/8th by 23 1/8th inch piece of 1/4 inch thick acrylic. After pondering on how to seal it, I remembered I had the adhesive velcro. Open... Closed... seals VERY tight. Octopus-proof standpipe. The internal overflow hasn't been installed yet (I'm waiting Marc... ) The workbench. The base rock structure for the tank. Waiting on acrylic rods and then I'll get some "mighty putty" and bond them together in the tank, after I get my overflow installed. For now I busted up some clothes hangers to hold the pieces together in holes I drilled in the rock.
