Growth is good. Looks like you have two spotlights pointed at it.

How long has this been going?

This pic is from my first ats 4 year old, i have build new one, the algae growth is similar and full of the screen,

Well this might be a rare case where dosing phosphate might help. You could try adding some Monopotassium Phosphate, which is just fertilizer.
