algae still in main tank

[SantaMonica]

As your scrubber get stronger, the bubbles pop one last time and go away.

I definitely believe it.
In the areas that the bubble algae was growing marginally (in bright upper areas), they have done that.

Unfortunately, still growing well in the dimmer areas. And my horizontal ATS is not really changing or improving.
I even tried adding a bit of iron.

I have been planning my Rev3 vertical. Might start building this weekend.
