You could put the water lettuce in a container outside the pond to give it
a
nutrient bath, then rinse and return to the main pond. Another idea is to
borrow plants for a day from a friend who has a pond? Where are you?

Hi, Wendy. None of my friends has a pond, although many are now considering
it after spending time on our deck and looking at and listening to ours. I
live in NE Ohio. I have begun to do what you suggested: pull the lettuces
and dose them independent of the pond.
Thanks for your help,
