how much sand you need to buy? you will have to ask the seller about dimension of their pack.roughly length X width X high cm = L. then you will see the volume each pack.
for eacj 1cm sand of you tank is 90X 60X 1cm = 5.4L that means each 1cm layer you will need 5.4L sand.
if a 20kg pack sand the volume is 10L ,the 20kg pack can fill you tank about 2cm thick sand base.
that needs some calculation work.
