Any chance that frogs and/or tadpoles eat duckweed?!

It's taken me years to get rid of the stuff on our pond, had to buy a
skimmer (Oase SwimSkim) in the end and that has worked so far. Never seen
any of our fish eat it, indeed when they gulp down a mouthful of pellets
and
accidentally get some Duckweed too they spit it out.
Maybe it's not carp that eat it.

Thanks, Bob. I'll look that up but probably not to be used until after
the
tads have hopped it?! We have all sorts in our ponds, some carp, some
goldfish, some goodness knows what. All seem happy and are breeding, so
something must be right. But the wildlife pond need the skimmer most so
I'll look at that once the spawn has hatched.

It will need cleaning out at least daily at first, then after it's removed
the visible duckweed and other floating stuff you can extend the clean out
period. There is always duckweed hiding in places to take over again.

As far as I can see, one flake of duckweed rapidly becomes thousands. It's
terrible stuff for spreading.

Ah, now that's interesting. The pond with no fish is the worst affected,
the pond with a few fish has some duckweed and the pond with loads of fish
has none. Thank you, Donna. The only problem is that we want to keep one
pond fish free so that other wildllife are safe from their predations.

Could you scoop up some of the duckweed from the fish free one and dump it
in the lotsa-fish one to give them a treat ?

Straw will clear it. Don't know about Frogs though.

It's quite a large pond and barley straw hasn't helped in the past - or
not
enough, anyway. I suppose we could try dragging some clumps of it across
the pond.....

Are we confusing duckweed Lemna minor with algal blooms and filamentous
algae which barley straw does control.

No, what we have is duck weed. And it's worst on the pond we don't want to
put fish into!

How about using a vacuum cleaner made for cleaning swimming pools

It would clog up in seconds and take the small but desirable things with it,
like frogspawn, newts, dragonfly larvae etc!

I'm not totally convinced they'd eat it. There are no grass carp in there.

My .75hp one I use to clean my pond needs priming and if it sucks in air, as
it would to remove Duckweed on the surface, it stops sucking and would need
repriming again.

A Vax would do it with no trouble - other than emptying it every fifteen
seconds.

We're stumped then, because we could only clear it when we are in

I see the problem has even made it to today's Grauniad. But they have
nothing much to say and no easy solution either:

I'd have thought it's possible that it's the fish that are keeping the
pondweed from growing on the fishy pool. But then, I've no experience with
ponds, fish or duckweed!

The message

I read on Internet that the only way to get rid of it is to empty your
pond and
scrub everything with bleach including the pump. If you miss just one bit of
duck weed you have wasted your time.

You read it on the Internet?

It *MUST* be true...

Why? It's designed for slurping as well as dusting, you know.

Have you a better idea or a reason why it wouldn't work?

(Your sig-separator's borked - this time - two trailing spaces...

Probably, it would work, but duckweed is not too difficult to keep in
check just by raking it off the surface.

Bleach in your pond paraphernalia will kill a hell of a lot more than
duckweed - and it's not certain that it will kill all the duckweed,
anyway, unless you really go over the top with it.

Thanks, Kate. That article made me feel a bit better because it does imply
that it has a couple of benefits! ;-) There's a strong wind blowing today,
so perhaps this will be my chance to gather up any that blows into a corner.
