According to Wikipedia Diatomite is a naturally occurring, soft, chalk-like sedimentary rock that is easily crumbled into fine powder. The typical chemical composition of diatomaceous earth is 86% silica, 5% sodium, 3% magnesium and 2% iron. Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae.
Not sure if this will be good as it crumbles easily. The media will be compressed over time and we need to transplant again. Wonder if the magnesium, iron and sodium might harm Neps or not.
