| Hi all, I have two tubs in which I grow miniature lotuses. One tub I had for 2 years, although i had no blooms, the water was always clear. This year I started a tub with some of my old lotus from the other tub into the new one. The new tub had this over on the top. Due to contamination from me , now both tubs have this on the surface. The lotus leaves seem to be healthy. But i would like to know what is this and how worried I should be.
Thanks for the input.

| It's duckweed. I recently noticed a small patch of it starting to grown in my pond as well- no idea where it came from. There are a lot of ways to get rid of it, but just skimming it out with a fine net is probably your best bet. |

| Not necessarily duckweed. Have you ever had Azolla (aka mosquito fern)? I think it looks like duckweed when it is just starting out. |

| Radha Looks like duckweed to me also. A very tiny floating aquatic plant. Harmless but grows like gangbusters lol. You can net it out but it does compete with algae for nutrients so is actually kind of useful , In your small areas not really a problem since Lotus have emergent leaves no competition at all . Your experience with lotus sounds like mine.. Get lots of growth, no flowers I built a 4x5 foot marsh garden for them but planted EVERYTHING but lotus .lol. Always thought the leaves very attractive even without flowers.. What variety are you growing?? gary |

| Hi Gary, If it is not harmful i will leave it alone. I tried cleaning it, but it comes back in 2 days in the entire tub.I have Momo botan and Chawan basu miniatures. Will it keep mosquitoes breeding under control too? regards, |

| Yep, its duckweed. Most people struggle to get rid of it , I wind up paying for it. The fishies, koi in particular chomp it up faster than it grows. |

| I would love to have a duckweed "problem". My fish see it as a special treat and it helps keep the algae down. Anne |

| Duckweed here is about six dollars for a 4 oz cup! Lucky you. A couple of hungry goldfish makes it hard to grow here. |

| Ditto here - I BUY Duckweed and can't get it to 'take over' because my goldfish eat it like candy - I even have trouble with Parrot Feather, they like to nibble the roots. |

| Radha You can just dip some out occasionally to thin it out . It is pulling nutrients from the water so IS keeping algae down. Only thing I've found effective for mosquitoes is fish.
