Excessive green weed in my Blagdon pond

[PAULYNORF]

Hi all,
I have a Blagdon upright pond with 8 goldfish. Fish are healthy and well. However this year due to the warm sunny weather we’ve had early I have loads of weed growing in the pond.
The issue is I don’t know what kind of weed it is to buy a treatment. It grows really quickly and I have to keep on top of it as it will take over if I leave it.
I have attached a photo. Sorry if it’s not clear but hoping someone can help. The pond does get a lot of sun but I have no way to shade it.
Hope to hear from you soon.

Best
Paul

Lots of string algae. Just take a clean toilet brush and wrap around the stuff and drag it out. I've heard hydrogen peroxide works but I've never had to use it.
