All plants produce oxygen turning the daytime.

Algae, which is what filamentous algae, or blanketweed,
is part of, is estimated to help produce between 70
and 87% of the world's oxygen that we use so I guess
we should treat it with more respect ;-)

I like anacharis the best of the underwater pond
plants. Far prettier than any of the other plants
but can be hard to get ahold of depending on where
you live.
