    WITH great difficulty! This small floating, light green fern will grow profusely in ponds and tanks and can regenerate with alarming speed from only one or two small pieces. It will be more of a problem in tanks that have an excess of nutrients, so sensible stocking, feeding, filtering and partial water changing will help.

    Goldfish will also eat it, but not as a first choice, so keep them hungry if you have this problem. Having said all this, it probably is true to say that the only way to eradicate duckweed is to physically remove it. Net it off, net it off and net it off again. Repeat this procedure about 500 times and you should be getting there! As you can see, it is easier to prevent the problem in the first place. If you spot a few pieces "“ and it is virtually impossible to keep it out completely "“ then remove it while it is still only one or two pieces.

    You know the funny thing is that I can't grow duck weed! Everytime this stuff gets in my tanks it never makes it. Can't say I know why as this stuff is apparently like a virus. I got some plants from Francois and they came with some 'complimentary duck weed', even this stuff is slowly dwindling away.

    Good luck

    lol, it's all about your viewpoint on it, one mans pest is another mans plant (was going to use the word weed instead of pest, but decided not to because of the double meaning)

    Duckweed is the question to many problems. If it had red in it, it would probably would be called "devil weed"

    Hi all,

    Duckweed can be menacing!
    I've always liked the look of duckweed until recently, when it almost suffocated my fish by preventing
    gaseous exchange at the surface! :eek:

    As this photo depics, on returning back from a 2 week vacation,
    the entire surface of my tank was overun by it.
    And to think, I started with only a single "2 leaved" piece of it. :eek:

    [​IMG]

    I resorted to netting ALL of it out, until not even a small piece of it remained.
    HTH

    Keep it at bay??? I got rid of every last bit of it! :gun2:

    I actually really like duckweed as a floating plant.But I despise the way it can potentially cause a
    disaster if not kept in-check.

    I went through great pains to get a bag full of Lemna Sp duckweed. I was a bit worried about placing it into my planted community as I wanted to use it in a future fry tank I still needed to setup. I decided to place it into my mixed community Malawi Cichlid tank in the meanwhile, hoping to see it proliferate a bit. I admired the nice new floating lawn I had acquired and went to bed. The next day returning from work, I noticed it had diminished significantly. I could not figure it out and though maybe the filter was sucking it up? The next day there was absolutely no Lemna left, with no hungry Cichlids clamoring for Dinner.

    They had eaten all of it up in a matter of days!
