DIY Live Rock for cheap

[Palooza]

I'm getting ready to do this for my pico. I am mason and much of this is in my garage. I also live less than a mile from the beach, so shells will be free.

 

Using sanded tile grout is brilliant! It does cure much faster than pure cement. 

 

So the indrediants will be sanded tile grout, shells, pool sand, & rock salt. The molds will be made of salt as well. It sounds like a solid week cure time and another 2 weeks of aerating in daily water changes will be a good cure time. I'll posts pics and updates on this thread. If you wanna check the pico build, I have a thtead for that started as well
