Algae/Green Water Problems in Koi Ponds?

What’s the best thing to rid Koi and goldfish ponds of algae and the muck on the bottom of the ponds? What’s good to keep the oxygen levels up?
or Any other suggestions for someone who has inherited these fish ponds.
Yes the ponds have a pump with filter system, there are UV light bulbs in the filter boxes. There are a few plants in each pond.
Any help would be appreciated. I read that a veggie filter works, anyone know?

pond owners swear by UV pond filters to help get rid of algae blooms. these blooms are caused by excess nutrients and sunlight. does the pond have a regular filter at the moment? water movement and filtration will also help.
