Remove as many as possible by hand. During a water change I would fill 2 - 5 gallon pails... pull the rock out, pull as many as possible off in to the garbage, then pop/etc the rest, and scrub as much residue as possible... Then rinse the rock in both buckets before going back to the tank.
Then get some (red elbow) Emerald Crabs
