So that’s dry rock. They’re a little evasive about exactly where it came from - there’s dry rock that’s been mined from ancient long dead reefs that haven’t seen water in millions of years: and there’s dry rock that’s basically made in a lab. My gut is this is the latter, as places that sell mined rock usually highlight that as it’s often seen as a selling point.Dry Reefrock 9 – 12Cm/ 1 kg – S&R Aquatics

This is what I was looking at.
I was talking to another place that said they sold dry reef rock, but they said it was man made.
I'm getting hugely confused with all these types of rock.
Anyway - no need to “cure” but you will need to “cycle”. This means adding bacteria and some sort of ammonia supply for it, then letting it stew in the tank for a week or two, testing to make sure the ammonia is being processed into nitrites and the nitrites are being processed into nitrates. Fish stores and aquarium supply sites all sell bacteria and cycling products.
