Just to be clear on the reaction:

H2O2 + H2O2 --> 2H20 + O2

hydrogen peroxide oxidizes itself or from another perspective, one
hydrogen peroxide molecule reduces the other... Mix in organic
compounds (fish gills) and H2O2 reacts to oxidize the organic
compound. Get the dose wrong and you burn the fry. Luis De Sousa was
using it as fixed ratio but I can't recall what it is...
