sjohnny8,
You have alot of ways to take care of this issue:
Get another fish, Get a refugium or stop feeding the tank.
Getting a fish that eats the algae while taking care of the algae adds to the nutrient issue. It fixes the issue without fixing the problem.
Get a refugium will take the nutrients out of the water thus fixing the problem of excess nutrients by removing them. But it does not address the cause. But it does work well cuz it creates a balance.
Figure out why you have too many nutrients in the first place. Over feeding? overpopulation? ... Then you wont need to compensate for the problem cua it will be gone.
First treats the symptom. Second is a treatment, third is a cure.
