Did you QT your LR before putting it in DT? Where did you get your LR from? What time of year did you get your LR?Its all a risk aefw have eggs on a frag plug what could they hide in 15lbs of live rock..
Its absolutely one way to go or the other "pest free" system and not, with any of those live rock options you automatically put yourself in the NOT line, they are not all bad but what do you want for your system if its just bio, then get the smallest flake of coraline algae or a few snails from a good tank, you already have bio. right you said your up and running? There's allot of things that you don't see on that live rock stuff that hasn't hatched yet and living deep in the rock
Like this guy(crab under plug) and a few others I missed, and the pistol shrimp that clicks all night long, that drives me nuts! I'm tearing the tank apart soon to get them all!
Just things to think about
