DIY reef rock

[EndAllTyres-Hoon]

I did see a post about diy rock but I wanted to show off my rock in its own post! I used 1 part fine aragonite 1 part crushed shell aragonite 2 parts Portland cement and 2 parts rock salt, thinking I need to go up on the sand and crushed shells, the sand covered lookkngnones were molded in used aragonite where the smooth ones were molded in playground sand, anyone else have any experience in making their own rock?

No, but I imagine the possibilities are endless.

They look good. I'm curious about the curing of the cement and leaching anything into the water. Have you used these yet?

Same as @Tob , I am also wondering how this turned out when you moved to the aquarium? How long did you let the rock cure for? I am planning on making some rock tomorrow.
