Thanks. The tank is around 3 months old, I have been doing bi-weekly water changes as I only have three fishes and around 5 frags. Should I start off using toothbrush to remove it followed by a water change?

If you can siphon it out that would be good. Your tank is new and your going to get a lot of algae, especially in the first year. I wouldn't worry too much about it.
