i use limestone for my "foundation" then some moon rock and tufa then my live rocks

about 3/4 of my rock in the FOWLR tank is "non-live" when started.

even $6/lbs still too much for my 135 gal

while you are at Ornamental and not afraid of silica, check out their white sand.
good deal @ $6/cubic foot
