You "neutralized" permanganate with peroxide?  They are both strong
oxidizing agents.  In fact, according to my old chemistry text, peroxide
is a slightly stronger oxidant than permanganate.  I'm surprised you
didn't kill more.

Hair algae can be controlled by removing it, adding algae eating fish,
increasing plant density and reducing nutrient levels, lighting periods
and lighting levels.  You didn't need to sacrifice your baby tears, shrimp
and whatever else turns out to have been fatally damaged leading to slow
death just in return for a partially successful, quick and dirty algae
