Tank Stand design... wall unit and sump that is longer than the tank....! where to support?

[Dukereefnz]

OK lets start with the tank size 36 x 24 x 24 (900 x 600 x 600)
I want a larger sump area (longer) than the tank, but how do i support it?
Also the external over flow is 145mm on the back and the wall unit must go against the wall so the back supports are not under the rear of the tank.
Lucky or un-lucky ( I say) this is a smaller size tank than many but still 85G or 325L = 325kg.

framing is 40 x 70mm
Main support beams are 145mm x 50mm (2 x under the tank)
Bench Top is 50mm wood less cut out for tank 25mm.
Front of tank is vertical under stand supports - back is not.
Overall wall unit length is 2200mm (86inh)
Steel angle supports at the front for extra support.

Tank is sunk in to the bench top 25mm..

I have down loaded inverter for free using my sons student ID... easy as and learned how to us it... obviously not well but I am trying..!
Sorry for all the pictures but trying to get me idea across.

Yeah it seems like you have the right idea. I've seen other reefers incorporate their reefs into a cabinetry system or an extended stand. Another option would be to move your equipment into a separate fish room if you have the space or just go with a slightly smaller sump.
