How to get rid of green soupy pond water"

[Fishnut]

Add a UV Sterilizer!!   I added it in the spring and took it out once the initial algae cleared, but the koi kept eating any kind of plant cover I added to the pond so in no time I could barely see them.  In the first pic, you'll see an orange blob.  That's one of the fish close to the surface.   In the last pic, I can finally see the bottom of the pond!!

Have you checked your parameters on the pond?

The first picture definitely shows suspended algae but in the following pictures, the water looks more brown than green. I am just wondering if something else might be clouding your water.
