Live Fish Stock
There are several natural ways to control and reduce algae growth in an aquarium:
Reduce feeding: Overfeeding can lead to excess nutrients in the water, which can encourage algae growth. Try feeding your fish only what they can eat in a few minutes, and remove any uneaten food.
Increase water changes: Regular water changes can help to remove excess nutrients from the water and reduce algae growth. Aim to perform at least a 25% water change every two weeks.
Add live plants: Live plants can help to compete with algae for nutrients in the water and can also produce oxygen, which can inhibit algae growth. Consider adding some easy-to-care-for aquatic plants such as Anubias, Java fern, or Amazon sword.
Introduce algae-eating fish or invertebrates: Certain species of fish and invertebrates such as Siamese algae eaters, nerite snails, and Amano shrimp can help to control algae growth in an aquarium.
Reduce lighting: Algae requires light to grow, so reducing the amount of lighting that the aquarium receives can help to control algae growth. Consider reducing the duration or intensity of the lighting, or using a timer to limit the amount of light that the aquarium receives each day.
It's important to note that while these natural methods can help to control algae growth, they may not completely eliminate it. In severe cases of algae growth, it may be necessary to use chemical treatments or other methods to control the algae.
