i curently have about 7-8lbs of live rock,my freinds tank went down during an ice storm last year and i picked up a piece of dead live rock from if i clean it is it safe to use in my tank for aquascapeing? thx nick
it will come back alive as long as the other rock in the tank is live. The currently live rock will "seed' the dead rock
I think many people get base or 'dry' rock when starting up a new tank, and then get a few pieces of live rock and use the cycling time to seed the base rock - I'll be using this method when I set up my tank in the near future
