Tank support question

Hi,

I am putting up a new tank with these dimensions:

24 x 12.25 x 20.5
19 Imperial Gall
22.5 US gal
85 ltr

I would like to know if the place I would like to put it will safely support the tank.

There is a sold wall which is 5.5 inches across and 24 inches long. To this I plan to secure a 3/4" piece of plywood which would exceed the tank dimensions by 1/2". The wall would run down the middle of the plywood shelf.

Thanks
