When I kept my tank at 70, I had duckweed clogged across the whole top. I started treating for ich (and increased temp to 80) and most of it has died back. I think it would probably be fine if I had a fan blowing on the surface but then I'd have to crank the heater up again to keep the temp up, and deal with all the extra evap. In fact all my floaters have been significantly melted, water lettuce, frogbit, and salvinia.
