I'm looking for some serious help with what to do with my pond.?

I sounds to me like the reason its green is from over growth of algea. My suggestion would be to add a plecostomus they love to eat algea. Also you could introduce snails that would help too. & usually pet store treat snails like pests so they would probally be happy to rid some to you. Im not familliar with pond plants sorry. But you can buy regular bunched aquarium plants & try them they don't cost mutch so would be a good {guinea pig} plant. If you don't want to try any of those then there are treatments you can get to remove algea. Good luck I hope I've somewhat helped you.
