Anyone know the more common name for this type of rock?

SAND DRAWING ROCK

Natural Stone Decor for Aquascaping. Delivery in 5 days.

The site is Austrian so I'm not sure if something is being lost in translation. It calls them "sand drawing rock", but a Google for that doesn't come up with anything that I can find. I love the look of them but want to do a bit more digging into inertness and potentially find some a bit more local.

Thanks.

Don't think I can delete my own thread (or if I can, I can't work out how) but I'm fairly sure I've managed to answer this myself. I think it's Gobi Rock or Gobi Desert Stone

Makes perfect sense! Thanks

They do look like Gobi dessert stone, though the limestone variety. I would expect these to raise the KH and pH, though by how much I don't know. Cannot be positive by just looking at pictures.

Thanks. I wouldn't buy anything without seeing it in person first. More so that I know what to look for and ask for when I go into a store. Given what my local stores normally stock, I suspect I'll end up with lava rock...
