Been out of the game for about 10 years, decided to get back in with a 29 gal.Couple of questions,first on rock, i like the dry rock for couple of reasons, fewer problems on curing and can start with purple rock. Next if i start with dry rock and live sand, what’s the curing process, and does it make any difference on which sand and salt you start with it they are both quality.Thanks for the help.
