Where's the link? Anyhow, the tank I'm getting has full black acrylic cover in the back (looks sharp!), floating glass cross bars unlike the plastic bracing Allglass has, black silicon seal, and the glass top rises above the overflow but the canopy covers it. It also has a beautiful stand with height / level adjusters at the base so that the tank will always be levelled.
It has neat thoughtful features that I don't see in other common tank brands.
