Rock ID help please

[Cornishlass]

Ok. I've got some rock. I can see some are dead corals and other is dry live rock ( I think). Then there are 3 pieces on the end which are a less porous smooth looking rock.

These are the 3 pieces that I'm not sure are suitable?


This is the rest which i think will be suitable? It will be cured before adding to the tank.

I'm not sure what you mean by "Rock ID"

Identification. ☺

The first three rocks look like limestone. They might be ok, depending on where they were before going in your tank.

They were in a tank that was changed to a tropical set up. They have been stored. Washed by me today. They will be dried and stored until I'm ready to cure the rock.
