I think there is a misconception when people buy LR, When they call it "live" they are not saying it is going to be covered in corals and snails and crabs, what you are paying the money for is mainly bacteria and worms and pods (that you won't see). THe most important feature of LR is inside, deep inside, there is an anearobic zone where nitrates are broken down and processed, this is the single most imortant feature of LR IMO, if that wasn't there then you might as well just buy mainly baserock. Over time you should see lots of pods and worms on your rock, but in general you will not see a lot corals and snails and crabs, most die in transport. There are exceptions, FL aquacultured has a ton of living stuff on it, but it is so dense I wonder about its ability to convert nitrates.
