Some species don't seem to be as prone to sending out floating leaves
as the others.  I have one that has remained submerged for four years
at least.

As others have said, pinching off the floating leaves may help.

Nymphaea will reproduce vegetatively.  Occasionally, more than one
plant may grow from the same tuber, and you can then divide the tuber.
The plant can also grow other tubers.  It can flower in the aquarium
and produce seeds.

No, I'm not saying that you need bright lights to benefit from CO2.
CO2 will usually help even with moderate/low lighting.  What I did say was
that having very bright lighting without adding CO2 was not something
I'd recommend.
