That was the hardest thing for me. It's surprising how strongly your
mind will resist the idea of *adding* nitrates and phosphates - things
you have been told to get rid of for years. After I finally decided it
couldn't do anything worse than increase the size of the algae, I tried
it. Then the algae went away.
