Welcome to Pond Boss from deep east Texas. You have a very nice setting. Looks like a algae problem for starters but you need to start at some basics. Find out how deep it is to know your volume of water. That will be handy for pond chemical treatment if needed. How many fish to stock, what size aeriation system, etc. Try to fish and determine what if anything is living in it. Try to take a water sample and get it analized. Others smarter than me will be along soon with their advise. Good luck and again WELCOME.

Dear Alcohol, We had a deal where you would make me funnier, smarter, and a better dancer... I saw the video... We need to talk.
