Hi,
Im new here, this is my first question, please be gentle

I have what looks like orange scrambled egg on top of the pond, it is a
well established pond of about 8 years, ive never seen this before, and
as fast as i take it off it comes back.

Is it some sort of algae?
How can I get rid of it?

Ive just finished a 3/4 water change, scooped what i can out, the pond
is refilling as i type.

thank you so much in anticipation
