Interestingly, after experimenting with U. gibba, I've discovered that you don't really need to drop the water levels to get U. gibba to flower. Dropping the water level will work, but you can actually get U. gibba to flower without doing that: I've got a tank of U. gibba which is flowering non-stop and all the U. gibba is floating on the surface, at least 5 inches above the peat at the bottom of the tank. I'll upload a pic when I've got time to snap one, things a bit hectic now.
