That all depends on what your definition of what "Live rock" is. For me it's rock that has beneficial bacteria living on it. The other stuff is just filler.
If you add any sort of clean up crew at all then you will be seeding the tank with coralline algae. And if you truly want to have those little critters such as pods
in your tank, it's as easy as adding them later on down the road. There's hundreds of places to buy copepods for your tank. In fact, doing it that way will save you hundreds of dollars and a lot of headache by avoiding undesirable hitch hikers like bristle worms, coral pests, flat worms, Nudibranchs, Aiptasia, Mojano, hydroids, mantis shrimp, and vermetid snails.
Every time I have to go into my tank to inject vinegar into aiptasia or having to go in and kill vermetid snails I kick myself over and over because it would have been prevented by paying 1/3 of the price for dry rock.
