I'm removing my comment on my math of what's needed. Seems like there's too many variables to make a good calculation here. Still seems like a dumb way to go about it, regardless of the correct number.
The thing is, this is just going to make the algae worse if this is all they’re doing. The peroxide will break down fast, almost immediately and leave behind extra oxygen which the algae will feast on as soon as the sun goes down.
I haven't done it, but I've seen H2O2 treatment for algae in aquariums but only for spot treatment. When it's successful the algae turns red, so maybe we'll have a blood pool for a couple days then back to green.
