Looking for free-floating plant species

While the local library has a lot of books about microalgae and
surface bound macroalgae, planktonic macroalgae/plants are – if at
all – only mentioned in foot notes.

I'm looking for plant(including algae) species that are at least 0.4mm
large and tolerate the following habitat:

- free-floating, completely submerged
- 10-30 °C (usually: 16-23 °C)
- 5-8 pH (usually: 6.5-7.5 pH)

Salinity (in-)toleration isn't an issue.

Thanks for any hints/ideas.

============
I have both hornwort and anacharis in my ponds. Both float just under
the surface. Hornwort sinks to the bottom of the pond when weather
turns cold. I don't know if they meet all your criteria, however, but
you can easily find references to them online. My water source tends
to be alkaline (7.2-7.5 range).

I hope you keep at least one Marimo Ball in your freshwater aquariums!

Keep them the size you want by just dividing them when they get big.
