These algae, also known as filamentous algae, can affect the aesthetic appearance of a pond and negatively affect the water quality. Filamentous algae often grow in dense, green mats that attach themselves to plants, stones and other surfaces in the pond. Their growth is promoted by a combination of nutrients in the water, especially phosphates and nitrates, as well as sunlight and rising temperatures. The risk factors that promote algae growth include too many fish in the pond, feeding with low-quality food, direct sunlight or fertilizer that gets into the water, as well as leaves and pollen from plants in the immediate vicinity.
