a small pond warms up quickly and that's when the algae grows. It's not harmful, the wildlife don't mind. Some people swear by barley straw, someone might explain how that works. I don't know. I have a large pond and still get algae.
Chemicals and filters aren't really part of a wildlife pond but it's your pond to treat as you like.
