Ha ha ha hahah ha.
This is brilliant.
They would need to put about 1,200 of those bottles into the pool to start killing the algae, which at the rate they're going would take about ten hours.
But then you'll have a pool full of foamy, murky, rotting green-brown sludge, released cell contents, possible cyanobacterial toxins, and a nutrient-rich soup ready to grow the next disgusting bloom, which will reappear within days, because peroxide will only last in that water for a max of two days, so they'll have to do it all again.
At a cost of $30k of chemicals each time.
They're literally dumping hydrogen peroxide into the reflecting pool this morning... 😳
