I guess it really depends if you care about the risks or if your local water is unsanitary or adds chemicals often. Climate also has something to do with it.
P.S.-Riley and ChestnutMoray are absolutely right about our lfs. :D
It probably is. It's in their display tank so you can bet your balls it's cured. :lol: or their idiots if they put uncured LR in their display tank.
P.S.-can't you put in uncured LR in your tank when your starting out?
It really just depends. If you have one that matches the fish's natural enviroment then it's probably better but if it's like a underwater castle or something gay you probably shouldn't use it.
