[AndyBill]

does anyone know what this weed is in my pond?

i keep removing it but grows back straight away!

does it harm koi carp or goldfish?

should it be removed or left as shade for the fish?

cant rem whats its called....but you will never get rid off it..it does no harm..but it grooooows + grooows

thats duckweed.

only 2 ways to get rid of it

1) empty pond and take it out leaf by leaf

2) over fill pond and let it float away


option 1 is impractibable


option 2 is dasngerous for the koi, since you will be using tap water, but its the easiest, and watch ph / amonia levels of water

breezer...just 1 piece will cling to a plant + you are back at square 1

Looks like some form of duckweed, but it seems yellower than I remember.
It will completely cover your pond if it is.
Clear it on a regular basis to control it.

Beaten to it..............

i know that, thats why you should do option 1, but option 2 is easier

you can't twirl it out on a twig?

You're thinking of blanketweed, which grows on the sides in direct sunlight.

This stuff looks like individual little buds floating on the surface. Regular Sweep over with a net would keep numbers down.

maybe that high-velocity tortoise will eat it.

I've still got it - could arrange to send it over.

 

[noseall]

I have this duckweed in my small pond. Its harmless and gives shade to the fish. You never get rid of it completely but just skim it off with a net every now and then. The birds bring it in from other ponds so it a lost cause so to speak. I think it looks quite attractive if controlled.
