LisaCGold 1,691 Posted March 4, 2016 You'll want to quarantine the duckweed for at least 5-7 days or longer, changing water daily. I grow my duckweed in my shrimp tank. At each water change, I take out some duckweed and quarantine it before putting it into my goldfish tank. Within an hour in the fish tank the duckweed is all gone. Duckweed is easily grown. You can put it into a container with water from a water change of your fish tank. Give it some light, but not too bright, and over time it will multiply relatively quickly. 0 Quote Share this post Link to post Share on other sites
shakaho 6,312 Posted March 4, 2016 While "better safe than sorry" makes a good rule, I think you might be able to feed your duckweed without a prolonged quarantine. I suggest you ask the seller if the duckweed was grown with fish. If not, I don't see it needs a quarantine. I just scoop the duckweed from the container into some used tank water, swish it around, then scoop it into a second container of tank water. Parasites and pathogens do not multiply outside of a host, so are unlikely to be in the duckweed water. Even if there were fish in the duckweed pond, huge dilutions like this will decrease any disease organisms that might be in the water to insignificant numbers. 0 Quote Share this post Link to post Share on other sites

I sent a message to the seller just in case When it arrives, I'll make sure to give it some good swishies in tank water. I'm looking forward to growing it so I can have a constant supply of deliciousness for the goldies. 0 Quote Share this post Link to post Share on other sites
amoonklein 1,212 Posted March 5, 2016 The seller responded very quickly and indicated the duckweed wasn't grown with any fish or invertebrates. Just plants and water. Also! The package arrived today! It wasn't supposed to get here until Thursday as it was shipping from Florida, so this was definitely a pleasant surprise I also received more than I ordered. Wahoo! I've already put it in a separate bowl of tank water and then took a tiny bit, swished it again in some more tank water then added that little bit to Hef's QT. He seems to like it 0 Quote Share this post Link to post Share on other sites
