I have a duckweed FIX. It consists of two words

SHOP VAC

Yup, I have a small 2 gallon SV and taped a smaller 3/4" filter hose to the intake, and it SLURRRPPSSS that duckweed right up! It takes me a couple of "visits" to the tank to get it all, but I have successfully wiped it out in two tanks. It gets those annoying pests hanging out in the corners, it just cannot hide!

Just be careful with those top dwelling fish, I have to chase my endlers from the intake, silly fish.

That's a pretty brilliant idea, I have a lot of issues with duckweed. Now, I just need to figure out how to chase all my shrimplets out of the duckweed.

Im going to give that a try today and see if I can make all of mine go away.

I like my duckweed. I like to think of it as extra fish wastes that I can just scoop off the top of the tank.

also, my fish seem to like hiding under it.

Great fix, but how about blatterwort? Solve that and the mad props come a flying.

Sorry, but give it a month or two and that tiny spec that You missed up between the glass and the top frame--will start it all over again.

I use comet goldfish instead of a shop vac, but the end result is the same.....

That stuff's a plague........

Ditto what Naja said. I'll bet you missed a piece somewhere, and it will come back to haunt you again. Ha, ha, ha, ha.

No, seriously, I hope you got it all. I'd do the same thing, but that would require lugging the shop vac upstairs and I'm just too tired for that.

Stay with it for a few days, you can get it all. Anyhow, it slurps it up quickly, which still beats netting it.

Honestly: stay with it for a month or two at every WC and You might beat it. The stuff is amazing. It will stick somewhere and dry up, but once it gets wet again--it starts all over! Sheesh! If You keep at it--You'll beat it, but don't let Your guard down for a while.

The Goldfish work 24/7, and I've left them in there for a +month after "its all gone"--nope, no such luck!

Im actually wanting duckweed......yes I know odd isnt it lol.....but now if it gets out of control I got a solution lol.

I tryed the shop vac thing tonight and I have to say that I ended up getting about 99% of it. I will give it a couple more days and then do it again and hope that I got it all. Plus I will do that at my WC also.

Someone search the archives. I posted the very same thing about 3-4 years ago.

I really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really hate duckweed. That stuff is like horror movie bad guys....just wont die.

i never considered netting it out difficult

Man, I just found that duckweed is starting to infest one of my non planted tanks... I don't even know where the hell it came from!
