I can't find the #@&! cord for my phone! To answer a POLITE question, eurobracing is basically strips of glass attached to the top edge all the way around to prevent the need of a center brace which can block a good bit of light. As far as your tank I think that at 20" tall a 6' tank of 10mm would need some sort of bracing. Now to all of the IMPATIENT folks I'll give a little rundown before I get pics up. The tank actually measures 60"L x 24"W x 32"H not 36" so nominal volume is 200 gal. Two corner overflows. Tank is constructed of 3/4" glass, Starphire front and sides, all edges beveled. Construction of this tank is serious overkill. I truly think that if you replaced every piece of glass with an identical piece of acrylic the tank would be sound. The bottom is a 3 layer sandwich with bracing inside and out, the tank is eurobraced and has a 10" wide x 3/4"thick center brace! The center brace and all of the eurobracing on the left side are cracked. There is some minor chipping at the corners from being moved about but nothing easily noticeable. This thing is HEAVY! Easily 600lb. I routinely deliver and setup tanks that hold more water than this one by myself, but this one took 3 people to get it into my truck off of a loading dock and 2 people with a set of ramps to get out. Getting this thing onto a stand will be a 4 person affair. Thankfully it's currently strapped down to a dolly which makes moving it a breeze. Pics when I find the cord or get my hands on a cam.
