10mm Gravel from a landscape gardening place should do the trick - 20kg for about 3-4 quid. i bought some from a pet shop the other day and they told me themselves it was just ypical stuff. to be fair i didnt need a lot so i just got it from there.
with regard to sand, i am thinking of putting a small amount in my tank as i want to vary the substrate [i already have two different sizes of gravel] my advice above is probably the only thing i have a clue about! and i have only had my tank for 2 months at most and am learning as quick as i can!
