    So of course all my duckweed didn't survive the cold. I was going to buy more online and kinda grow it using the pond water. I heard of concerns about the duckweed carrying bacteria or viruses especially when coming from other water that may have had fish.

    Does anyone have a certain way of making sure that stuff is clean? I was going to put it in a small transparent open container of pond winter for the winter and leave it indoors.

    Just transfer it to fresh water every day for a few days. Things that might infect fish have no reason to stick to duckweed. In fact things that eat bacteria, like rotifers, like to hang out on duckweed, These make great fry food, so fry appreciate duckweed long before they are big enough to eat it.
