Frogbit is hard to come by. And it is not an easy plant. I had it covering my 90g for weeks, then suddenly, it died off. I now have a couple feeble plants in another tank. This may be one reason why it is so difficult to find.
Ceratopteris cornuta is ideal. You may find it planted, it will grow planted in the substrate or floating; it grows best floating. But it is available, if not in stores online.
Duckweed is just that, a "weed." It works fine, but being so small it does not have the usefulness of Ceratopteris and other floating plants. Salvinia is similar but a bit larger and more attractive, but not easy to find either.
Another option is to use a stem plant. My 90g is presently covered on the surface by Brazilian Pennywort. This makes an ideal floating plant, the leaves will face up at the surface, the roots will grow downward and longer, and the plant does very well.
