Algae grows in water exposed to light. Block the light, and you won't get algae growth.

Chlorine?

Our drinking water is clorinated and that's what comes out of the garden hose too.

Chlorine is good at killing bacteria, but not so good at algae. Just ask someone who maintains a pool.
If you put it in at levels that kills algae, you will certainly damage a lawn.
