I got a great deal on 23 lbs of fiji from someone downsizing, it does'nt seem to have any critters and stuff on it , but the coralline is great and where it's not coralline it's a nice bright white, what i want to do is put this rock in a temporary tank to keep it in this shape until i get a handle on my main tanks nuisance algae problem (hair and green film) If i was to set up a tank for the sole purpose of this rock, what is minimum i would need to do it? Would i need to use any aged water or is all new ok?
