DIY rock?

I missed how the rice/pasta salt makes it porous?

the idea is that after the concrete cures, the rice/pasta/salt decomposes or dissolves and leaves holes behind.

Good luck, Tony! Let us know how it goes.
 
I think I'm going to make preforms with the aquamend and then mound the mix of concrete/crushed coral/rice around it. Going to have a little fun with odd shapes
 
Hmm... aquamed would be an expensive mold. Tony, have you thought about superglue and dry sand. I think that's what I heard about someone else using.
 
I'll see if I have any pictures of when I did it 9 years ago :) I still have some of the power head covers I made sitting in my sump.
