New Barrel pond stringy web-like weed?

We have setup a wildlife pond in a half barrel. It has been setup for a week and a bit. Rain water from a water butt used. Native plants bought online, now in bags with gravel on the aqua soil. It is not in the sunniest spot (morning and late afternoon - about half the day). What could the stringy, green, weblike stuff which is now on the Hornwort, Creeping Jenny, edges of the bags etc? If I move a plant I can see it and it’s quite strong! Any ideas appreciated. Anna

    The little solar fountain is only on when in full sun.

    It's just algae. Perfectly normal in a new pond  :)
    It's a place where beautiful isn't enough of a word....

    Thanks for this - will it take over? Or just a phase? Thanks!

    Hi Anna
    It's a type of algae called blanketweed and will appear in new ponds.
    Given your pond is quite small, I'd just run my fingers through it and gently pull it out and off the plants.
    It will disappear of its own accord as the pond settles and your plants get going.
    It's nothing to worry about.

    PS- always try and use rainwater to top your pond up. The minerals in tap water will encourage more algae.

    You can just pull it out, or there are over the counter treatments. You can also chuck in watercress which  feeds on the nutrients that the algae likes too.
    Once the pond settles a bit, it becomes less of a problem though. It won't harm anything in there.

    Another thought - You'll probably notice the sides of your pond get covered with a green fur - that's also a type of algae.
    If you can get a few pond snails, they'll keep the sides of the pond clean and they'll multiply quickly too.

    You can compost the blanket weed.  Its scientific name is Spirogyra, because of its helical chloroplasts.  You'd need a microscope to see them.

    Not sure if this will update you, thank you pond-knowledgable people! Algae seems to be stopping - I did take out some. Now a new development, plants under the water seem to have been eaten? But all we can see is mosquito wrigglers? Any ideas what would eat away the leaves to nothing? And put holes in other leaves? Thanks for any help!

    I can only see these creatures on the creeping Jenny although these does also seem to be an equally tiny slug-type creature? Could they be responsible?

    They look like little ramshorn snails.
    I have them in my pond as well as pond snails.
    I've not known either to eat any foliage, but they do a really good job of keeping the sides of the pond clean and plant leaves algae-free
