The skimmer may help, but I wouldn't spend much money on one in that size tank. I hear the ones for the biocube can be very hard to adjust to work properly. You may want to make a separate post about them in the equipment section.
If it's almost part of the rock then it's probably not a bad algae. Its the slimy stuff that you don't want to see. Anything that encrusts the rock is likely to be beneficial. I bet you don't have a problem at all!
