Alfagrog is man made: It is a highly porous ceramic filter media specially created for bio filters in the fish farming industries. (Also known as Supra)

Lawa rock is the natural by-product of lawa.

Good quality Lawa can be on par with Alfagrog, but you get various qualities. Some is not porous enough, some is too soft and blocks your filters as it breaks up.

Alfagrog is normally much better, but also much more expensive.

In my experience, Alfagrog is far superior because of the millions of airpockets, big and small, ideally suited for biofilm growth. The rings that I know, for instance loolitubes, do not have as many air pockets and are much denser.

Alfagrog:
