My tank is 20" deep 12x39w (six each side),most of my clams are on the bottom. Have some sps in the lower half of the tank too. You shouldnt have a problem running 6x54w. Depending on what clams you were thinking of, crocea and maxima prefer to be on rock anyway. So, unless you find a super flat rock to put them on at the bottom of the tank, they will likely be up a bit.
