i was reading this article about making live rocks,,using aragonite sand mixed with aragonite gravel and white cement..its seems easy to do,,and you can get as creative as you want..i just wanna know if anybody has ever done it and if its a good base rock to grow corals and coralline algea

it takes a while to cure but my next tank is going to have these man made rocks to fit exactly as I need. where did you get this info? I got it from Geothermal Aquaculture Research Foundation Home Page

I've made some just out of curiosity since I already have 3 Lbs/gal in my tank. The things that I noticed was that 1.) It takes a long time before it is ready to put in your tank. 2.) It is heavy if you don't add stuff in the rock like rock salt or noodles to create voids. 3.) Coraline grows good on it if you use crushed oyster shells or plastic shavings in the rock. 4.) IMO, it doesn't seem to have the critters in it like real LR does and I'd be concerned about its nitrate reducing capacity if you don't already have close to 2 Lbs/gal of true LR already.
