In order to make it possible to distinguish and compare we must define what is considered “living stone”, we must define being alive. Any piece of rock placed in a biologically active medium, such as an aquarium, will soon become “alive”, covered with life.
To me, "living rock" is a piece of rock covered with what is called "periphyton" or "aufwuchs", it is covered with a mixture of dead and living growth of all kinds of organisms. The stone is covered with microbial mats, microbial communities. The added value must be sought in the origin of the stone, as it is transported over very long distances.
It is clear that when one speaks of “living rock” in the literature, they don't always talk about the same thing, especially when referring to “treated living rock”, so-called “cured live rock”.
A piece of living rock that meets my definition can therefore just as well be a piece of rock that has been in an aquarium for some time and has not been overgrazed. For my definition, porosity plays little or no role. The surface actually useful for biological processes is compared.
It would be interesting to know what is your definition of " live rock" and what would be the added value of such rock compared with my definition.
