I've also seen tanks with Val. planted in sand and every time I've seen the

The most I can do is shake the gravel vac above the sand substrate. This
causes turbulence which detaches the detritus matter from its resting
place and then goes straight up the tube. If I dig in I'll decapitate
some leaves.
