What is the issue or question? : What type of filter should I use/How big must it be, to filter a algae-ridden pond? Like, how many m2 of water/hour should it be able to "produce". My filter seems to small, or maybe the pond too dirty.
You could try a UV sterilizer, but Im not sure how well that would work with a pond. Here are some ways to get rid of algae.
Limit how much you feed, More frequent water changes(10% a week is what most pond owners I know do for normal water changes), More plants, Put some shade over it.
The usual recommendation for ponds is a pump that turns over the pond volume at least once every two hours. I am still learning about filtration for ponds myself, but so far what I have learned is most ponds hold more media than aquarium filters. so because they hold more media, the water needs to pass through slower.

My apple snails make almost as much waste as my goldies do. XD
