Oh I am no where near done bracing lol
I will be adding 3/4" plywood triangles to every corner about a foot or 16" long
there is also gonna be 2-2X6 cross braces about a 2 1/2 ' feet in on both ends an then I got 2- 2X10 cross braces in the middle
I am also designing the canopy to be one massive brace Its hard to explain but when I get there I will post pics
an for added brace the tank is gonna sit tight to one exterior concrete wall an one main support wall so they are added strength
Also where ever wood touches wood I have used construction adhesive (PL Premium) to add extra bonding as well as sinking wood screws every 4 "
I am also finishing the outside of the tank with 2X6 tounge an groove pine boards
the inside plywood is 3/4" an the the outside is 1/2" or 5/8" I cant really remember
as for the floor its a concrete pad the tank sits on an I made a 2x6 floor system with the joists running every 12" an that is all glues an screwed
as for stocking I completly agree with ethnics on the feeding costs I ahve a buddy who built a 1020 gallon tank here is the link
