Ok, sooo I've read a lot of the forums here and got a lot of useful information. I finally got my tank set up. Not much going on in it right now cause it's two days old. BUT here's my question, I have like 12 lbs of rock in there right now, it's only a 15 Gal tank soo I want to buy some more rock but want to do it cheaper. I plan on cycling my tank for about 30 days before I do anything to it so Was wondering if I could buy plain base rock and put it in with my live Sand and the live rock I already have. Would it then become live as well? If soo, How long would that take approx? Is this a recommended practice?
