Nothing good happens fast in this hobby. However, if you load up a media sock with some GFO (many of our sponsors carry it please try to purchase from them if possible :), Bulk Reef Supply is probably the cheapest), you will see an improvement. Then I would make sure you have a few snails to deal with the issue. I recently had a some hair algae growing on the sides of my tank. I added two small turbo snails to my 29 biocube and within a week, the algae was completely gone. I didn't do anything else.
A few other questions for you:
How long have you had this tank? Sounds like you got it already setup and moved it? Did you reuse the substrate? If so what is the substrate. What size biocube is it? How many fish are in there? How often and what do you feed?
