I know forsure that a cycled tank and curing rock is different. I think I had a thread on here that was titled cycled rock vs cured rock and myka gives a good talk. I think I'm convinced with such a small price difference in used and rock from the lfs I'm going to use quality rock. I think an article like that would be great because at one point I was searching for that topic. Would 20 lbs of live and say 10 lbs of dry pack my 20g to full? I won't have a sump untill I build my own stand.
