You sure have a beautiful place. Just some thoughts. KOI I believe would help with the algae but on the other hand you want clear water and they are a carp that will stir the bottom. Coontail will clear the water and add oxygen but can grow out of control. They could be controlled with grass carp, but not muddy the water I think. The green tea is most likely photoplanton that is beneficial for lower life and adds oxygen but clouds the water. I've had no Algae this year using plants and Golden Shiners and have fairly clear water with a little tannin color but so many plants that I have aren't for you I think. I expect the experts will say to aerate and use chemicals.
