Hey guys and gals, I want comments, pictures, and opinions on the DIY rock. I watched videos and researched it. Making 3-2-1 or just winging it in some threads of making rock out of salt, concrete, and crushed oysters with a sand mold. Let's hear it guys! I am aware that it is a timely project but yet the weight in rock and the artistic customizable properties of it are a major plus. How does it hold up in setups over time, Coraline alge, how does it handle growing on this rock? Do the fish like it, what about the anemones or LPS corals. Ect....any suggestion, opinion, or experience is welcome.
