Where does the reef on Tarkhankut come from? It is dry, yes. But the fact that it is a reef... well, you understand.

This is Crimean cavernous sandstone or tuff.

Basically, I also put shell rock in the aquarium and everything lived fine, but there it's a whole train with a trailer, can you handle it if something goes wrong? On the other hand, I also put Black Sea stone in my aquarium - the results are in his thread.

With natural live rocks, based on the dead skeletons of corals, do not confuse. When you collect at least 65-70% of such live rocks, then you can also add these. Just remember, live rocks for reef building must be truly alive, not smelling like dead matter, and then enriching your aquarium with nitrates and hydrogen sulfide. If you place the stones shown in the photo without natural live rock, there will be countless problems with lower organisms. Good luck.
