how can I kill green algae in a swimmingpool?

smack it hard with oxidant (chlorine treatments). Floc it afterward and sweep it out. This is not a new problem at all.

Either by removing their nutrition or by filtering through an UV sterilizer. Neither method is guaanteed to work, though.
You also might try poisoning the water - but then again, woud you rather swim with green algae or in poison?
