Do you have an aquarium? If so, you may have noticed an increase in dark green or black algae. This is a sign of Black Beard Algae, an invasive algae that can quickly take over your tank.
Don’t worry – you can eliminate it with the proper knowledge and care. You’ll learn about the causes, symptoms, and ways to prevent and treat Black Beard Algae.
So, let’s get started – did you know that over 90% of aquariums will experience an infestation of Black Beard Algae at least once?
Identifying Black Beard Algae
You can identify Black Beard Algae by its dark green or black color and hair-like or beard-like appearance. Commonly attaching itself to aquarium plants, decorations, and glass, it can rapidly cover large areas if not controlled.
Insufficient lighting, high levels of organic and fish waste, imbalances in nutrient levels, and inadequate water circulation can all contribute to the growth of Black Beard Algae. Overfeeding fish can also increase the risk of its development.
To prevent Black Beard Algae, maintain proper lighting, balanced nutrient levels, regular water changes, adequate water circulation, and appropriate CO2 levels.
Without proper preventive measures, getting rid of Black Beard Algae can be difficult once it is established.

Causes of Black Beard Algae Growth
Uncontrollable growth of Black Beard Algae in your aquarium can be caused by:
– CO2 fluctuations
– Too much light
– Overfeeding
– Poor water quality
– Overdosing fertilizers
Monitoring and maintaining these factors in balance is essential to prevent it from occurring.
CO2 fluctuations
Fluctuating CO2 levels can cause Black Beard Algae growth in your aquarium. You must maintain appropriate CO2 levels in your tank to control this algae. Too little CO2 will cause an imbalance, leading to rapid growth of the black brush algae. Too much CO2 can also cause an imbalance and lead to red algae growth from the same family.
1. Inadequate CO2 injection: If you inject CO2 into your aquarium using a CO2 system, fluctuations in CO2 levels can be caused by a malfunctioning or inconsistent CO2 regulator. Ensure that your CO2 system is working properly and that the CO2 output is consistent.
2. Insufficient CO2 diffusion: The method used to diffuse CO2 into the water can impact the stability of CO2 levels. If the diffusion method is not efficient, it can lead to fluctuations. Consider using a diffuser that provides a fine mist of CO2 bubbles or a reactor that ensures proper dissolution of CO2.
3. Poor water circulation: Inadequate water circulation can cause CO2 to accumulate in some areas of the aquarium while being depleted in others. This can lead to fluctuations in CO2 levels. Ensure your aquarium has sufficient water flow and is evenly distributed throughout the tank.
4. Lack of surface agitation: CO2 can escape from the water surface, especially if there is inadequate surface agitation. If the aquarium water’s surface is calm, consider adding an air stone or a surface skimmer to enhance gas exchange and prevent CO2 buildup.
5. Overstocking or overfeeding: Excessive fish population or overfeeding can increase organic waste production. The decomposition of organic waste consumes oxygen and releases CO2, causing fluctuations in CO2 levels. Maintain a balanced fish population and avoid overfeeding to prevent excessive CO2 production.
6. Plants and algae consumption: If you have a heavily planted aquarium, the plants can consume CO2 during the day for photosynthesis, which can cause CO2 levels to drop. At night, when the plants respire, they release CO2, leading to fluctuations in CO2 levels. Similarly, excessive algae growth can consume CO2 during the day and release it at night, causing fluctuations. Properly balancing the number of plants and algae in the aquarium can help stabilize CO2 levels.
A water change can help correct the levels, but regular maintenance is the best way to prevent Black Beard Algae. Treatment for Black Beard Algae should include:
- Manual removal.
- The introduction of algae-eating fish or invertebrates.
- Adjusting lighting and nutrient levels.

Fluctuating CO2 levels can impact the growth and development of black beard algae (BBA). Here are the reasons how fluctuating CO2 levels can affect BBA:
- Suboptimal CO2 levels: Fluctuating CO2 levels, especially if they are below the optimal range for aquatic plants, can lead to the growth of BBA. In low CO2 conditions, BBA can outcompete other plants for nutrients and light, thriving in such an environment.
- CO2 imbalance: Fluctuations in CO2 levels can create an imbalance in the aquarium or aquatic ecosystem. Rapid changes in CO2 concentration can stress and weaken other plants, making them more susceptible to BBA infestation. This can lead to the overgrowth of BBA without healthy plant competition.
- pH fluctuations: CO2 levels directly affect pH levels in water. Changes in CO2 can cause pH imbalances, which may favor the growth of BBA. BBA tends to thrive in slightly acidic to neutral pH conditions, and significant pH fluctuations can enhance its growth.
- Altered carbon availability: Fluctuating CO2 levels can affect carbon availability for plants, including BBA. Inadequate or unstable carbon availability can hinder the development of other plants while providing an advantage to BBA, as it can adapt to low-carbon conditions more efficiently. It’s important to note that while fluctuating CO2 levels can contribute to the growth of BBA, they are not the sole factor responsible for its presence. Other factors such as nutrient imbalances, lighting conditions, and water flow also play a significant role in the growth and control of BBAp.
Too much light
Frequently, too much light is the cause of Black Beard Algae growth in your aquarium. To prevent this, create a lighting schedule that provides 8-12 hours of light and 12-14 hours of darkness daily.
Black Beard Algae Information
| Causes of Black Beard Algae | Effects of Black Beard Algae | Removal of Black Beard Algae |
|---|---|---|
| Too much light | Covers plants & decorations | Lighting schedule |
| Imbalanced nutrients | Blocking out light | Hydrogen peroxide |
| Inadequate water circulation | Manual removal | |
| Low CO2 levels | Algae-eating fish/invertebrates |
Overfeeding
Feeding too much can cause an imbalance in nutrients, leading to Black Beard Algae growth. Overfeeding a tank with fish food can increase the amount of fish waste, uneaten food, and decaying matter in the water, all of which can encourage the growth of Black Beard Algae.
Uneaten food will also reduce or even stop the growth of Black Beard Algae with the right amount of food. To kill Black Beard Algae, aim to feed the fish no more than they can consume in about two minutes.
Remove any uneaten food after two minutes, and consider feeding the fish smaller portions more frequently. Doing so can help maintain a balance in the tank and reduce the risk of Black Beard Algae infestations in your aquarium.
Poor water quality
By monitoring the water quality in your aquarium, you can help prevent the growth of Black Beard Algae. Poor maintenance, such as infrequent water changes, can lead to an imbalance in light intensity, nutrients, and CO2 levels.
To prevent the growth of black algae in aquaria, set up a regular maintenance routine. This includes frequent water changes and testing for key water parameters.
Filtration is an important part of maintaining water quality in the tank. Be sure you are checking the cleanliness of the filters. You can do it in every water change.
Remove the uneaten food, fish poop, and plant debris as much as you can.
Overstocked aquariums will lower the quality of the water. This will lead to algae bloom.
Overdosing Fertilizers
Overdosing fertilizers is one of the main causes of black beard algae growth in aquariums. Excessive amounts of nutrients, specifically phosphorus, can create a nutrient imbalance, encouraging the development of black beard algae. Maintaining a balanced nutrient level is important to prevent this invasive species’ growth and get rid of stubborn black beard algae.
It is important to differentiate black beard algae from staghorn algae, which has a different appearance. Preventing and treating blackbeard algae will help maintain a healthy and balanced aquarium environment.
Water Circulation
Poor water circulation is one of the leading causes of Black Beard Algae growth in aquariums.
- Nutrient Accumulation: In areas with stagnant water, nutrients can accumulate because they are not evenly distributed throughout the tank. Algae thrive on these nutrients, such as nitrates and phosphates, which are byproducts of fish waste, uneaten food, and decaying plant matter. Improved circulation helps distribute these nutrients more evenly, reducing the concentration in any area.
- Oxygen Levels: Poor water circulation can lead to uneven oxygen distribution within the tank. Algae, like all plants, require oxygen for respiration (especially at night), and inconsistent oxygen levels can encourage disproportionate algae growth in some regions of the tank.
- Carbon Dioxide and pH Levels: Algae need carbon dioxide (CO2) for photosynthesis during the day. Poor circulation can lead to uneven CO2 levels, and it can also affect the pH balance of the water. Areas with higher CO2 concentrations might see more algae growth. Moreover, stagnant water can lead to lower pH levels, which can also be conducive to certain types of algae.
- Temperature Regulation: Proper circulation helps maintain a consistent temperature throughout the aquarium. Inconsistent temperatures can stress aquatic life and contribute to favorable algae growth conditions.
- Dead Spots: Poor circulation often leads to ‘dead spots’ in the aquarium where water is almost stagnant. These areas become ideal for algae to anchor and grow, as they are less likely to be disturbed.
- Waste Removal: Good circulation is essential for moving waste products to the filter for removal. In poorly circulated tanks, waste can settle in certain areas, providing a constant nutrient source for algae.
Ways to Get Rid of Black Beard Algae
You can get rid of Black Beard Algae in your aquarium by following these steps:
– Introduce algae-eating fish.
– Use hydrogen peroxide to kill the algae.
– Perform regular water changes.
– Add aquarium plants.
These steps can help to reduce the spread of Black Beard Algae and keep your tank in balance.
Which fishes eat Black Beard Algae
One of the best ways to eliminate Black Beard Algae in your aquarium is to introduce certain algae-eating fish or invertebrates. These include:
Sucking Fishes:
* Siamese Algae Eater
* Otocinclus Catfish
* Flying Fox
Grazing Fishes:
* Hillstream Loach
* Molly Fish
Invertebrates:
* Nerite Snails
* Malaysian Trumpet Snails
These species can help to control the growth of BBA in your planted tank, and prevent its spread to other areas in the tank. They should be accompanied by proper lighting, nutrient levels, water circulation, and CO2 levels to reduce the causes of black beard algae in fish tanks and the effects of black beard algae on aquatic plants.
Algae control products can also be used as a last resort.
Using Hydrogen Peroxide
For an effective way to eliminate Black Beard Algae, try using hydrogen peroxide. This type of algae is a common problem in many aquariums, and hydrogen peroxide can be an effective solution.
To use hydrogen peroxide to remove black beard algae, follow these steps:
1. Prepare a hydrogen peroxide solution: Dilute 3% hydrogen peroxide with water in a 1 part hydrogen peroxide ratio to 3 parts water. For example, mix 1 cup of hydrogen peroxide with 3 cups of water.
2. Turn off any filters or air pumps in your aquarium to prevent the hydrogen peroxide from getting diluted or dispersed too quickly.
3. Use a syringe or dropper to apply the hydrogen peroxide solution directly onto the affected areas of black beard algae. Be careful not to overdose the solution, as excessive amounts of hydrogen peroxide can harm your aquarium’s inhabitants.
4. Leave the solution on the algae for about 5-10 minutes, allowing it to work its way into the algae and kill it.
5. After the allotted time, gently scrub away the dead algae using a clean toothbrush or a small brush. Be cautious not to damage any plants or disturb the substrate.
6. Once you have removed as much algae as possible, change the water to remove any remaining hydrogen peroxide from the aquarium.
7. Monitor your aquarium closely in the following days to ensure the algae does not return. If necessary, repeat the hydrogen peroxide treatment after a few days.
Hydrogen peroxide treatments should only be used as a last resort for stubborn black beard algae. It is important to address the underlying cause of the algae growth,
Additionally, some aquarium inhabitants, such as certain invertebrates, may be adversely affected by hydrogen peroxide, so it is crucial to research the compatibility of your species before using this treatment.
Adding hydrogen peroxide to aquarium water can help get rid of Black Beard Algae by killing the algae and preventing it from spreading. Using hydrogen peroxid can be harmful to fish and aquarium plants. It should only target the affected surfaces and never be poured directly into the fish tank.
Water Changes to Prevent Black Beard Algae
Regular water changes are essential to prevent Black Beard Algae from taking over your aquarium. Doing so will help maintain a healthy balance of nutrients and create unfavorable conditions for algae growth. Here are a few tips to keep in mind when performing water changes:
– Test tank water regularly for imbalances in nutrients such as phosphates and nitrates.
– Introduce algae-eating fish, such as audouinella, siamese algae eaters, and Florida flag fish to help control the growth of Black Beard Algae.
– Use a gravel vacuum to remove any algae that has attached to the substrate.
– Perform regular water changes to keep nutrient levels low and discourage the growth of green water algae, brush algae, and Black Beard Algae.
Add aquarium plants
Besides manual removal and introducing algae-eating fish, another way to get rid of Black Beard Algae is to add aquarium plants. Planted aquariums are a great way to prevent the growth and spread of Black Beard Algae. Aquarium plants cover fish and invertebrates and absorb excess nutrients that mainly cause Black Beard Algae. They also help to reduce the number of algae spores in the water, which can prevent the growth of Black Beard Algae and other nuisance algae such as hair algae.
What plant helps with algae?
Certain aquatic plants can help control algae growth in aquariums or ponds by competing for nutrients, light, and space, thereby creating an environment less favorable for algae. Some of these plants include:
- Hornwort (Ceratophyllum demersum): This submerged fast-growing plant absorbs a lot of nutrients from the water, which can help outcompete algae.
- Water Wisteria (Hygrophila difformis): Known for its rapid growth and ability to absorb excess nutrients from the water, making it harder for algae to thrive.
- Duckweed (Lemna minor): A floating plant that shades the water, reducing the light available for algae, and absorbs excess nutrients.
- Java Fern (Microsorum pteropus): A low-maintenance plant that can thrive in low-light conditions, making it a competitor for algae.
- Anacharis (Elodea canadensis): This plant grows quickly and absorbs a lot of nutrients, which can help control algae.
- Java Moss (Taxiphyllum barbieri): It competes with algae for nutrients and can be used to cover surfaces where algae might otherwise grow.
- Marimo Moss Balls (Aegagropila linnaei): These unique algae forms compete with other algae species for nutrients.
- Amazon Sword (Echinodorus bleheri): A larger plant that can help balance the nutrient levels in the water.
- Vallisneria: This plant grows tall and can shade certain areas of the tank, reducing the light available for algae.
- Water Lettuce (Pistia stratiotes): A floating plant that shades the water and competes with algae for nutrients.
Also, some floating plants (like Lilies and Lotus) provide significant shade over the surface of the pond. By reducing direct sunlight, they help control the growth of algae. Algae typically need sunlight to thrive, so shading the water can significantly reduce their growth.
Submerged Plants (like Anacharis, Hornwort, and Parrot’s Feather) are often referred to as oxygenating plants. They release oxygen into the water through the process of photosynthesis. This oxygenation is beneficial for the overall health of the pond and its inhabitants. Additionally, these plants compete with algae for nutrients and light, further helping to keep algae growth in check.
Freshwater fishkeeping can be a rewarding hobby, but taking proper steps to prevent and control Black Beard Algae is important. Adding aquarium plants is an effective way to get rid of Black Beard Algae, but proper maintenance and appropriate lighting are necessary for the plants to thrive. With the right setup and care, aquarium plants can provide fish and plants with a healthy and balanced environment.
Fish and Plant Impact
Black Beard Algae may not harm fish, but it can still impact them and plants in the aquarium. Its black, hair-like, or beard-like appearance can block out light necessary for photosynthesis, causing plant leaves to turn yellow or brown. New fish can also bring stubborn algae species, such as Red Algae, which can be confused with Black Beard Algae. Aquarium owners should be on the lookout for this type of algae and take steps to remove it if it starts to grow.
Many fish produce waste and uneaten food that can contribute to the growth of Black Beard Algae. If the aquarium isn’t properly maintained, black beard algae can grow quickly and cover large areas. It’s important to note that black beard algae benefits fish, as it provides hiding spots. However, it can still be a nuisance for aquarium owners. It should be removed from the aquarium in the first place.
Manual removal is the first step to do this. Use a toothbrush or algae scraper to scrub affected surfaces gently. Introduce algae-eating fish or invertebrates to feed on the Black Beard Algae, and adjust lighting and nutrient levels to create unfavorable conditions. Chemical treatments or algae control products can then be used as a last resort.
Prevention Strategies
Preventing Black Beard Algae from taking over your aquarium can be as simple as staying on top of maintenance and monitoring water conditions. Algae in the aquarium can thrive if the right conditions are present, and they’re usually introduced via aquarium items, plants, and fish.
Also known as brush or black algae, Black Beard Algae feed on the nutrients used by the aquarium inhabitants and algae to fortify their cell walls. Proper lighting is essential to prevent an overgrowth of Black Beard Algae, as it needs enough light to expose the algae but not enough to encourage growth.
Maintaining balanced nutrient levels and CO2 levels is also important for prevention. Regular water changes and adequate filtration will help to keep the tank clean and the water healthy.
