    Looks like a sponge of some type... I have seen this before and usually just take it off before adding the rock to the tank.

    Looks like a mix of algae and sponge, I would definitely remove it.

    If this is a new setup and you are just beginning the cycle I would probably leave it. A sponge exposed to air will die and will help with your cycle. IF you are adding rock to an existing tank, especially a lot of rock, then I would scrub the rock with a brush in a tub of old tank water before adding it.
