I know you're looking for live rock but if you want pest free, which I think is more important, start with dry rock and let it ferment in your sump. I've added a lot of dry rock in my system in the past with no ill effects.
BRS dry rock. Don't rush it and let it cook.
Their Pukani is more air than rock - perfect!
Title says it all, preferences please? looking for some rock to add to sump for a dead rock tank. Looking for real live rock that is as mature and pest free as possible.
