Default How to collect clean rainwater?

Hello Jo

Just a tight fitting lid. Algae needs sunlight to live. Insects need
access to lay eggs. You can stop both with a lid.

Lids commonly sold at garden centres for the common sized butts, btw.

But tbh, green water with larvae in isn't going to hurt your
houseplants.
