Moral of the story…. Back in the mid 90’s, I know I’m old, I started tanks with real live rock plucked from the ocean sold at the lfs. I also used saltwater that was pumped from the ocean and sold at the lfs. Both were cheap and abundant at the time. Over 20 years, no pests, no tank crashes, no real ugly stages, some would just call it luck. My first new tank, with over 20 years under my belt, Marco rock, bare bottom, ulns….. let me tell you, I’ve had every problem known in the universe with this thing for the first two years! Three years in and it’s finally stable and taking off, but now I’ve lost most my vision so I can’t enjoy it! I think it’s always been safe to say that real live rock is the way to go, or cooking it…. Funny about that is I remember the rc days of people actually cooking or boiling rock! I don’t think the seeding of a dry rock tank with a bio brick from someone else’s sump is necessarily bad, but I haven’t seen it jump start a tank as much as was touted. I also remember purple up and that was the best way to start coralline, we’ll I guess not. I also remember live sand being the best way to start a tank…. Guess not, a raw shrimp the best way to start a tank…. Guess not, there’s too many to list and all were on certain video series from certain vendors…and all touted as science
