Does anyone know what this pond weed is, and how to get rid of it without killing the wanted pond plants and insects please? 
Not the best pictures, but stuff grows like mad and covers the pond, constantly trying to remove it.
Unfortunately came with some frogspawn my brother gave from his pond for our kids to watch.

I used this stuff https://cloverleaf.uk.net/blanket-answer
I got a tub off Amazon, definitely works very well/quickly and only needs using very infrequently.

Hoik it out, give the snails and various larvae a day or two to get back into the pond, then dispose if it.
Barley straw is supposed to work, but I've never had much success. Water lilies work better for us.
That's interesting as our water lillies are quite ineffective against blanket weed.Barley straw is supposed to work, but I've never had much success. Water lilies work better for us.

Thus year, the blanket weed is bad because back in March. I pulled out about half a ton of lilies as they were taking over.

It contains a 'unique blend of minerals and enzymes'. So as to how it works, we're no further forward.
You can easily pull blanketweed out by hand for free, and it's instant.
Unfortunately if you grab it and pull it out it has a habit of just growing back again from all the bits that stay behind.You can easily pull blanketweed out by hand for free, and it's instant.
I don't know how that stuff works, all I can say is that it definitely does.
Often caused by not having enough planting covering the water surface to create shade, allowing the sunlight into the water which encourages it to grow. It. Covering 2/3rds of the surface with planting can help. Duckweed (dreaded by some) does a great job of shading the pond and preventing blanket weed developing.
I actually quite like the look of a pond with duckweed, and it does help keep the water nice and clear. I no longer scoop duckweed off my pond, and as it's a wildlife pond I'm happy for it to find its own balance.

Difficult to tell from the photo but "blanket weed" is just some sort of mat forming algae?
If so, it's usually a result of excess nutrients in the water. Do you regularly top up the pond with tap water?
No, I think it came from my brothers pond when he gave my kids some frog spawn in a bucket which also had weed in it.If so, it's usually a result of excess nutrients in the water. Do you regularly top up the pond with tap water?

I seem to recall reading it's manganese. Whatever it is, it works, I use the same product. You can easily pull blanketweed out by hand for free, and it's instant.
I've been pulling out armfulls of it for months and this stuff sorted it in a couple of weeks.
