Pond Is Sunny Position

Question

Hi my pond is in a sunny position and too well established to move we keep getting green algea despite trying various treatments & turning water blue. We do ha a variety of plants in it as well! Do you have any suggestions please

Answer 1

Do you have surface plants, too, such as water lilies? You can cover up to 50 percent of the surface water with lilies. The shade will reduce the algae and the fish will appreciate it. Also, fertilize plants as little as possible and don't overfeed the fish. Excess nutrients will only feed the algae.
