It's worked well for me in the past, but I've had
problems. If you overdose, you can wipe out a lot of
the bacteria that fix ammonia and nitrites. I ended
up with a rather nasty nitrite spike the last time
I used H2O2 that wiped out 15 shrimp.
Delicate plants didn't seem to like it much either, the
leaves on my Micranthemum umbrosum all turned translucent
and the stems fell apart.
I tend to avoid H2O2, if/when I get a really nasty
outbreak I'll resort to good ol' erythromycin. [yes, i'm
the concerns re:resistant strains, if anyone cares I can
outline why i think this is overrated.]
In general, if I have good plant growth cyanobacteria
can't get started. Once it gets past a certain point,
nothing short of massive intervention gets rid of it.
