Algae

[Bobfish]

Hi All
The water in my pond is very clear and the goldfish are quite happy but there's a green algae (I htink that's what it is) growing on the sides.
Can you advise how to remove this or whether I should just leave it. As I say the water is clear and there is a pump and filter fitted.
Here are some pics. Thanks in advance.

Your water is clear, that's great. At least you don't have green water from floating algae.

It looks like blanket algae. I get that in the Spring.

As my plants grow, they out compete the blanket algae and it goes away.

So, the cure is lots of plants. If you have a lot of plants already, they just need to mature.
