BINGO...

No light will temporarily eliminate it, but it will come back if you haven't
changed the reason you got it in the first place (water parameters).

this is getting confusing, I have read and been told that blackouts
kill the bacteria because it needs light to live and that a two to
four day blackout should kill all the bacteria in an aquarium. are
you saying that blackouts cannot work?

The blackouts will kill the chlorophil in the bacteria, but not the
bacteria
itself. Once this is done you then have to make sure all your water
parameters are right, and keep them that way, or it will just come back
again. To get rid of it completely you have to kill the bacteria.

Read the rest of this thread, you will find there are more ways to deal
with
this than you will have time to try

And that's why I said kill it first, then add the KNO3 thereafter.
You need to remove or kill(cause senscence) whatever is there, THEN
correct the issue which was poor plant growth(NO3 limited plants).

This is true for any algae/plant combo. Remove the algae/kill it etc,
then correct the plant growth problem.

Even if you managed to kill it all with drugs, 30 days later you'll
have air born in your tank again unless you practice sterile technique
and have the tank sealed/filtered air etc.
