Off the top of my head, my first design ideas starts with a small to medium tank. I would add a removable black plastic plate about 2 or 3 inches from and parallel to the glass at the end of the tank.
It would go from front to back but would not reach the bottom and not go all the way to the water level. A bubble bar, place between the plate and the glass would forms a wall of bubbles that should cause a gentle role of the water in the tank and should agitate the algae strands to break down the boundary layers. Hopefully this would increase the efficiency of the algal growth and nutrient uptake.
