No, I dont have any diatoms or cyano. Im thinking of adding a HOB Refugium.. Do you think this will stop the algae from growing?

The refugium will help with the nutrient uptake by competeing with the algae. Have you considered getting a sandsifting gobie for the tank? They do a great job of keeping the sand clean as they turn over the sand fairly quickly.
