I have used Carribean or "Florida" LR
, obtained from a LFS
and online, in my tank to add to my current LR
, I would not consider it for cycling a new tank. The benefits are that it is aqua-cultured and comes with a very nice variety of visable life (can be good or bad, depending). Because of this, a lot of the life may not survive the cycle. I would go with cured or uncured LR
, such as Fiji, from one of the sources Mike mentioned. After your tank is up and running, go ahead and source out some top-shelf carribean to add to the tank.
