Seamed edges is what most glass cutters do just to make the edges safe to work with. No special look to them, but dull to the touch. So you won't cut yourself or anything else. Not sure if its the same as Polished.
Floating around in the tank are some Red and White Mangroves I will be using in the sump. The red need to soak in the water for a few days; then will be transplanted in some potting soil mixed with some of the aquarium sand (mixed together with the tank water).
Finishing touches to come shortly (includes moving the TV =p )
