Flat $10 bucks shipping so get a few things.

The bleach dip was to ensure I didn't add any unwanted organisms into the tank. I gathered it from a location that has a large number of waterfowl and invertebrates.

Yep , thats the place. I’ve ordered from him several times and was always more than satisfied.

Duckweed is the worst plant in the industry.
Luckily, for some odd reason, it doesn't do well in my tanks.
I added it to one of the ponds on purpose. 1 month later and half of what I added is gone.
I guess thats a good thing.

I can’t kill it. I have it confined to a ten gallon sitting in a North facing window and no light fixture. I have to thin it regularly. It has its uses but everyone seems to either hate it or tolerate it.

Just for completion.....

not quite sure what a Tropica in-vitro pot or plant is.. do you mean like growing kits, or lab grown plants..?

Tropica is a Danish plant grower, so their plants are probably not available in the US. Besides potted plants, they also sell tissue culture plants, referred to as in-vitro plants.

There are several European growers who procude in-vitro plants, but I don't know if there are any American growers.

Never mail plants internationally. Because of possible pests, there are a lot of controls and the fines in many countries would be serious.

I throw away half a kilo or more of duckweed every second week, and I thoroughly hate the stuff. In my multi-tank set up, it does very well indeed, and if you miss one piece, it returns. There are lots of floating plants that don't become pests, and when I see someone looking for duckweed, I cringe. It's like seeing someone seeking a disease, to me. Guppy grass. Riccia. Even brittle old hornwort. Elodea. Anything but the pest with a million cousins!

Honestly, if any of you were around here, I would give you fish, plants - no problem. If I have them, I share. But I would not give a person duckweed, as I would not give a person a cold on purpose.

Yes, I am a bit lazy, or I could spend the equivalent of several days gradually eradicating it. My rainbows got rid of it in my main tank, and I have Pistia growing indoors under a window and outcompeting it in a paludarium tank. It removes nitrates and provides fry cover, and apparently, it pleases ducks,. I am no duck.

Fair point above. I don't think about a lot of things..

Frogbit or salvinia. They grow just as fast, gobble up ammonia but have bigger leaves and don't stick to everything in your tank

Thinly way to kill duck weed is to reduce nutrients so much that most plants will not grow. The best way to remove duck weed is to daily remove all of it that you see in the water. Keep doing that until you go 2 to 3 weeks without seeing any. All you need is a very tiny fragment of one plant for it to come back. Another ting I found to be helpful is floating plants like salvinia or red root floatersIf you can get these larger floating plants to cover the entire surface any duckweed will get tangled up in between the larter leaves and when you remove the excess floating plants you will also remove much of the duct ed in the tank. I also found duckweed can grovertizlly and cover salvinia So if you let the red root floaters grown until you have a layer about 1/2 int thick any duckweed under it will likely dye due to the lack of light. And when you remove the plant you take out most of the dckweed.

Count me among the anti-duckweed contingent. I managed to eradicate it from my 55 gallon years ago and have avoided it like the plague ever since. I prefer amazon frogbit (Limnobium laevigatum) and floating fern (Salvinia natans).

I don't have a tank yet, but I am from an area where this stuff grows everywhere. First thing I thought was, "Duckweed? In an aquarium?" It is aggressive and can choke out a pond. I understand the benefits of it, though.
I wouldn't ship that stuff to anybody because it could easily become an invasive species.

Yesterday was duckweed removal day. Net loads of the stuff are now in my garden, frozen solid. Come Spring, I hope they add nutrients. In each tank, net sweeping probably got 95% of it, but it will be back. In two weeks...

It doesn't need a lot of nutrients. I have it in dimly lit 10 gallon killie tanks that contain single pairs of 1.5 inch fish, and have plants. Duckweed is the honey badger plant. It don't care. It overgrows in half darkness in lighty stocked tanks that get regular substantial water changes.

Ducks have a lot to answer for. I suspect that Scrooge McDuck got his millions from selling this weed.
