The page won't load for me, maybe because I'm at work. "Live" just means it has been cycled and hosts the beneficial bacteria that processes ammonia and nitrite. It also can have hitchhikers on it like starfish or what-have-you.
Personally I have never bought bulk LR
, I always buy dry "base rock" and cure it myself. That way I know there are no pests or anything bad in the rock. You also don't buy other peoples algae issues. Its also a TON cheaper :p
Its a personal preference, if its been in a nutrient rich base of SW
for more then 3 weeks, its probably live. You will get some die off from shipping though and will most likely see a mini-cycle when you get it.
Check our articles section for some good reads on cycling and curing rock.
