I take panty hose and drag it along the surface. Picks up a lot more than a net will.

Baby angelfish.

They eat the roots off.

Can't grow the stuff at all anymore. Wish I could.

duckweed is like herpies, once you put it in your tank it is almost impossible to get rid of like java moss as well

I've had luck going back and forth across the surface with a small net. Be sure to get behind your HOB filter if you have one. Be vigilant!

Had this happen a few weeks ago. I just spent 2 hours catching everything with a small net. No outbreaks. So looks like I'm clear.


You could also just setup a skimmer and have that do all the work.

duckweed i consider the worst invader in a planted tank. id choose algae any day

I got lucky during the early phases of plant stocking and got none, so I haven't added plants in years out of simple fear. once in my 75 g tank that had duckweed forever, a pair of simple gouramis for some reason chowed down on the fruiting stage or whatever it is when there are no leaves, just little bb's covering the surface that look like buckshot. I scooped most, they ate rest and it was clean till i just had to have that new ludwigia then it never did the bb phase ever [email protected]!!! the new ludwigia imported the flowering phase and I never won.

small old reef tank:

you can increase surface agitation and manually remove every piece of it from the surface with a net or something. be thorough and diligent

Take some airline tubing and make a horse shoe out of it. Float it in the water and let it "capture" all of the duck weed. Like they do when harvesting cranberry.

Nah - I have to be careful not to accidentally remove too much when I'm thinning it out. I could remove every bit of it from my 37 in 15 minutes if I wanted.

Get a goldfish for a while, then rehome it once it eats it all. Goldfish love duckweed.
