Tracing back a few steps.
I raise nitrates and it makes a considerable dent in the dinos.
Algae moves in and covers much of my rocks.
Dinos move back in and sit comfortably on top of the algae.
Cyano really gets going and covers the dinos.
Now I have less than 5% of the dinos left and would call that acceptable.
The algae on the rocks is fading as well.
I the past dinos out-competed the algae and it hardly grew at all.
My tank, a few weeks ago, with lots of algae did have lots of dinos as well at the same time.
