With enough H2O2, about 6,500 gallons in this case, they can definitely kill the algae (for a time being, the H2O2 won’t last long before breaking down, and then you’ll get another algae bloom). The dead algae will lose its green color and settle on the bottom.
The bigger question is how it will react with the algaecides that are also meant to be in the pool.
If the Trump team isn’t involved and it’s just NPS acting on its’ own, it might be well thought out: shock the pool with H2O2 to kill the algae and reset, then get ahead of the next bloom with a larger algaecide does to compensate for the warmer waters created by the darker bottom.
