Not quite about the piece on the top right, but the others look cool. Some interesting shapes that will allow the fish to explore, especially the bowl shaped one in the top left and the almost clam-shaped one in the bottom two.

What process did you use for actually making them? Looking forward to a build thread to learn more!
 
Yah that one is goin to be more of a base with a lil over hang. Glad u like the bowl that was my wifes idea. I ise the basic formula. With some minor adjustments. 3 parts crushed oyster shell 1 1/2 parts portland cement and 1 1/2 parts salt. Ive tried different sizes of salt to get different textures of rock. All seem to work fine. Im just makin alot of different shapes and sizes ill determine later which ones i us in the tank
 
i have anotehr mix that uses argonite sand. i think it would allow for a little bit more of a PH buffer then without
 
I use some sand in one i didnt like it as much. It made it heavier and not as porous
 
Does anybody know if u can add to a diy rock after it has cured
 
I don't see a problem with adding to a completed rock since it's so porous. Since it's not load bearing, I don't think you really have to worry about cold joints.
Ymmv.
 
if you let the rock soak liek its recommended, and what not it should be fine but i's say put it in a rubbermaid container and start a cycle and build a colony of bacteria on it before you add it
 
But if it had bacteria on it wouldnt it be harder for the new cement to cure to the old
 
Some updated pics
