, DIY rock just doesn't look as good as the real stuff. I always see home made rock and you can just tell that its man made. I hate when you can see human preference in aquascaping of real rock even. Its really distracting to me.
But if you do it, I would be interested to see how it turns out. It very well may be the future of SW
, lots of places are limiting or banning the export of dry and live rock.
