Goldfish need a balanced diet that includes various sources of protein and fiber and plants and fruits like peas and apples.
Therefore, if you want to keep your pond clear from excessive amounts of algae, it’s better to maintain a healthy balance between fish population size, water quality (elevated phosphates), water circulation (aeration & filtration), and regular removal via manual vacuuming or an automated system installed within your pond’s ecosystem.
