not much algae on live rock

[Zoaelite]

An excellent ID page is http://www.melevsreef.com/id/algae.html, right now if I were you (and it sounds like the tank is just getting started) I wouldn't worry too much about algae growth just make sure your parameters are proper and your cycling is done. You will have some sort of nuisance algae it happens to everyone so just sit back and enjoy the diversity ride, eventually once your parameters stabilize you will be good to go.
