Help, white fluff surounding my pond
I recently bought a house and it came with a pretty sizable pond that does have fish(I believe he said carp). I would really like it to be clear and visible and maybe eventually add some koi to it. My problem is the weeds and growth all around the edges. all the shallow areas around the edges have what looks and feels like long grass growing under the water and I also have a floating layer of white squishy stuff that is surrounding all the edges. I included links to pictures hoping that might help explain it better. Thanks in advance for any help because I'm having a real hard time figuring out what this growth is.
