I am by no means a structural engineer, or a craftsman, but I think I dont trust just biscuit and glue for these joints. You have close to 1200lbs a side pushing out on them. I would have put the sides on the bottom, if that makes sense. Or maybe at least some screws. Again, this is only my personal opinion.

biscuits are surprisingly strong... but I like my tanks overbuilt. I'd run 2x2's down the inside of the corners and screw the plywood into them.

Well done so far looks good. I would in some way beef the joins up on the corners though. I would say that the biscuit joints may hold out to start with but they aren't going to last that long IMHO.

How about using some angle bar on the outside of the tank and screwing through that?

:idea: yes, I'm going to try make them look like port holes in a ship.thought big panels on ends needed something, but didn't want to much glass, but in the end, probly be same amount of work.
does anyone know what type of glass I should get? safety glass? toughened or just standard?

the thickness of the glass depends on the depth @ which it resides....

The taller the tank, the thicker the glass

If its heat strengthened, you can go with a thinner glass...i think.
I am sure some1 will correct me if im mistaken.

Your standard 55 gallon that is 20" to 21" high and uses 3/8" thick glass.

Do some more research...check out garf's site

Also, tempered glass is hella expensive.... =(
