I have algae forming on my artificial putting green.

Does anyone know the best way to remove the algae without harming the turf?

I see methods online but I want it to be safe before I apply.

Most algae will come right off with a garden hose. The few algae that have an adhesion mechanism can be loosened by depriving it of light for a few days (with a tarp, perhaps) before hosing it off.
