Here is my pond this year. Finally a pond I am not totally discouraged with. The green water has never developed, I can see all the way to the bottom (4 feet). It is 3500 gallons with 2 Skippy Filters. I don't have many plants in the pond, just in the filters because I live in rural Nebraska and I get a lot of snakes, raccoons, etc in the pond it they have places to hide. I am using Green Clear for the Algae control and Pond Perfect beneficial bacteria. I do add some bluing (artificial shade) to the water because this pond is completely in the sun with no shade ever.
