Interesting.
What is the purpose of the rock salt? How are you going to lower the Ph of the cement? You didn't use any aragonite sand at all?

I didn't use the sand cause I didn't like the looks of it. Right now the "rocks" are still very grey but will lighten up in time. I will post a picture of one of the pieces tonight. As far as the ph goes, concrete once cured (6 - 8 weeks) will lose its high ph content. You just soak it in fresh water with water changes every day or 2.

Cool idea for making the rocks more porous.
It doesn't matter what color the rocks are, they will get covered in coralline algae anyways.
