The logical step is to treat the source of the problem, where the algae is getting its nutrients from. After that it would be to just deal with the algae itself, manual prunings, scrubbing the rock, etc. Although since I can't pinpoint the source I feel like I just endless go in circles.

1.5" of Gravel is a total nutrient sink. Under 4" willl not really act as a Biological filter at all.

Could you run Barebottom for a while?
