Seems to duckweed

I bought some moss from my lfs and seems that i got some more than moss, i saw floatting at the top of my one tank these two leafed plants and i googled and found the exact same thing.

Now can someone tell me more about it bad or ok?

Thanks

 

If you have positively ID'd them as duckweed... It depends...

If you have high nitrates and want them removed good...

If you don't want your tank instantly filled with it and blocking the lights to penetrate to your plants and growing like a weed.... Then its bad.

 

well put @hein24 it makes good food for some fish too.

 

id love some free duckweed for my tank...anybody in cape town got for me? want the lights dim for my frontosa anyway

 

@nodac, it also blocks your filters if not controlled so really be careful it is highly invasive.

 

depending on what type of filter you have that is. @nodac you should be able to get some for any petshop that deals with ponds as they are often found on top of ponds just like ducks (duck weed) lol

 

i have a canister filter so a surface plant wont make a difference to it. would like to get a decent amount to start off with and i havent seen any at perky pets or sams for sale

 

+1 don't flush them down the drain or let them somehow get into a local river, dam or pond.

 

Isn't it native in South Africa? Have this mess in all my tanks in Holland.

 

I'll send you a kilo !!!

 

It is an illegal weed here in SA !!!!

 

Ok it really is invasive indeed. I'd like to get rid of it. What are the SA-ducks eating than hahaha

 

Net mieies en brood haha.

Wish I could have a big bag of duckweed, my goldfish would love me.

 

Sho! Ducks would be drooling if they saw that :nuts: hahaha.
Don't want to derail the thread too much, but how often do you clean out all the duckweed before it regrow's to that @DoubleDutch?

 

Once a week.

 

Actually duckweed is now considered an endemic species here.

Best way to get rid of it is to keep removing it manually, or get fish that eat it. You just have to keep at it. It's a real pain in the youknowwhat to get rid of.

 

Just add it to your salad, it actually tastes quite nice. :blink1:

 

Really, where did you hear this?

Found this link, and looks like duckweed is distributed world-wide and can be found on all continents except Antarctica.
They speculate that Lemna minor might be native to North America.

 

I know this type of duck weed is Illegal in SA. lol
