Well you can use Siamese Algae Eaters or Amano shrimp to remove it. But you need to address what causes it in the first place.
You did not give any tank specs or water parameters but if you will supply the size of the tank, how many watts of light you have over it, your pH, kH, gH, nitrate, and phosphate levels we can give you more help. Also tell us how much and of what types of fertilizers you are using and how often.
