Uhm, that's abuse, sorry.

I have some concerns with this formula.  Isn't it true that certain
forms of brush algae can survive up to 5 mins in a bleach solution??
This is more than enough to kill most plants but yet the algae can
survive.  Another concern is are you bleaching just because or are you
trying to kill a specific organism?

I would assume so.  Seems to me that you would also have to account for
the stress the plant is under, the health of the plant and all those
other factors that can determine it's survival.
