What to fill Skylan stands with for Harbeth SHL5s


Skylan stands for SHL5s: could someone please tell me what to fill them with?
Skylan advised PURINA MAXX kitty litter, but I cannot find this in the U.S.
Should I use play sand, sand kitty litter, clay kitty litter, something else?
Thank you.

I custom made a stereo rack to match the Sound Anchor stands that my Spendor SP100's sit on. I filled 2x4,2x2,1x1 steel tubing with silica sand. Silica sand was plenty dense, heavy and dampened steel perfectly. Steel likes to ring.
