Generally, I don't. The sun does it for me. Algae will grow only
where the sun doesn't reach. In places where the sun doesn't shine,
I use a stiff broom and sharp sand[*].

Yes, but you DON'T want Pathclear to run onto plants and ponds. Weak
bleach may kill algae, but won't affect most plants (probably not even
mosses) - we use it to sterilise sprouted seeds, after all.
