Should I put duck weed in with my 10 gallon??

In a 10g it will probably take over the tank and get in your filter too much. If you want it for nutrient uptake in that size tank you should just get alittle water spite and plant it or float it. It grows fast in all types of lights and will suck excess nutrients like crazy. When it gets too big just cut it to the size/height you want it.
