They don't seem to. In face H202 is mentioned as a diseasse
treatment for fish in half the strength required to kill
algae. And a few years ago there was a company selling
a ceramic device that slowly leeched h202 into the water
as a "superoxygenator".

Hornwort seems to be the most sensitive. If you've killed
your hornwort, that's just enough.

Ranshorn snails seem to be the most sensitive animal I have;
the right algae killing dose is about the LD50 for these snails.
