Last summer I had a problem with a bunch of E. Tenellus that was almost
completely obscured by a black algae. One of the list members wised me up
that despite "Nitrate is a toxin" feeling one gets from reading most
aquarium keeping books, zero nitrates is also not a good situation. My
tank was N-limited.
I added enough KNO3 to reach about 5ppm and kept it there. A week or so
later I had to clean my filters almost daily because of the die off of this
It worked for me.
