starting to get algae, should i be worried?

46 gallons
96 watt coralife power compact

not sure on the algae type. its green and i only really notice it on the glass. pretty much wipes right off. i haven't seen much of an increase in algae over the last few days. plants are beginning to look a lil better. still gotta get ferts to dose N-P-K. where can i get dry ferts?
