I have your exact same problem in one of my tanks. The water movement at the surface pushes the dwarf water lettuce away from the light which is a 2 bulb strip that sits directly on the glass cover. It gets very little light but is real hardy. I mainly keep it as food for the Buenos aires teteas. The prefer it over other plants in the tank. It's ugly because the roots break off from the flow and the leaves are yellow and half nibbled on, but it serves its purpose. In my smaller tank with higher light, no plant eaters and a calm surface, it grows like mad. I haven't done a water change in a month in my HEAVILY stocked 10 gallon and the nitrates are only 10ppm. I attribute that to floating plants.
