Blue Green Algae In Planted Aquarium
Introduction
Blue-green algae, also known as Cyanobacteria, is a type of bacteria that can be found in many freshwater environments, including planted aquariums. Although it is not a true algae, it is still commonly referred to as such because of its appearance and behavior. Blue-green algae can be a major problem for planted aquariums, as it can quickly take over and harm the plants and other aquatic life.
Causes of Blue-Green Algae
There are several factors that can contribute to the growth of blue-green algae in a planted aquarium. One of the main causes is an excess of nutrients in the water, such as nitrates and phosphates. These nutrients can come from overfeeding fish, decaying plant matter, and even tap water. Another cause is poor water circulation and a lack of oxygen in the water, which can create stagnant areas where blue-green algae can thrive.
Identifying Blue-Green Algae
Blue-green algae can be easily identified by its appearance. It typically forms as a slimy, green or blue-green film on the surface of the water or on plants and decorations in the aquarium. It can also appear as small, green dots on the glass or substrate of the aquarium. In addition to its appearance, blue-green algae can also have a foul odor and can cause the water to become cloudy.
Preventing Blue-Green Algae
The best way to prevent blue-green algae from taking over your planted aquarium is to maintain good water quality and provide proper filtration and circulation. Be sure to not overfeed your fish and remove any decaying plant matter or uneaten food from the aquarium. It is also important to regularly clean the aquarium and change the water to remove any excess nutrients. Additionally, adding live plants to the aquarium can help to compete with blue-green algae for nutrients and oxygen.
Treating Blue-Green Algae
If blue-green algae does appear in your planted aquarium, there are several methods that can be used to treat it. One method is to manually remove as much of the algae as possible and increase the water circulation and aeration in the aquarium. Another method is to add an algaecide, but this should only be used as a last resort as it can harm the plants and other aquatic life in the aquarium. It is important to address the underlying causes of the blue-green algae growth to prevent it from returning.
Conclusion
Blue-green algae can be a major problem for planted aquariums, but it can be prevented and treated with proper care and maintenance. By maintaining good water quality, providing proper filtration and circulation, and adding live plants to the aquarium, you can help to prevent blue-green algae from taking over your aquarium. If it does appear, be sure to address the underlying causes and use appropriate treatment methods to ensure the health and wellbeing of your aquatic life.
