Although the amount of algae harvested has been increasing slightly over the last few cleanings, the progress is slower than I expected, especially the amount of GHA.

May be flow across the screen is not enough, and/or not enough iron?

That is a perfect example of the growth being best where the intensity is highest. You can totally tell where the lamp is. I don't think I've seen a more definitive picture! It's a good thing that you spaced the lamps so close, or else you would get larger areas of darker growth. Very well designed!

Just needs more light. Or more time.
