You can probably get waterborne algae either way, but longer hours is

If you add snails, you'll get more waterborne algae, but the daphnia will
probably do a good job of clearing it too.

Nah. Just put a few snails in. You should already have waterborne algae, it
just needs an advantage over the filamentous algae. The snails will quickly
multiply and consume the algae, leaving your tank a nice fertilizer soup. The
waterborne algae won't be able to resist growing, although the daphnia may
consume it as fast as it grows.
