The world of aquarium-keeping is a fascinating one, filled with the wonders of marine life and the thrill of creating a thriving underwater ecosystem. However, even the most experienced aquarists can fall victim to the pesky problem of brown algae in their aquarium. Brown algae, also known as diatoms, can quickly take over a tank, covering rocks, plants, and even decorations, making it difficult to maintain a healthy and visually appealing environment for your fish and other aquatic inhabitants.
But what causes this unwanted growth, and more importantly, how can you prevent it from happening in the first place? In this comprehensive guide, we’ll delve into the world of brown algae, exploring the various factors that contribute to its growth, and providing you with the knowledge and tools you need to keep your aquarium algae-free.
What is Brown Algae?
Brown algae, also known as diatoms, are a type of phytoplankton that thrive in aquatic environments. They are typically brown or golden in color and can range in size from a few micrometers to several millimeters in diameter. Brown algae are harmless to fish and other aquatic animals, but they can still cause problems for aquarium owners by covering the tank and making it difficult to maintain.
Brown algae are particularly common in new aquariums, as they are attracted to the high levels of nutrients present in the water. They can also be triggered by changes in water chemistry, such as sudden drops in pH or increases in temperature.
Causes of Brown Algae in Aquariums
So, what causes brown algae to grow in aquariums? There are several factors that can contribute to its growth, including:
Overfeeding
One of the most common causes of brown algae is overfeeding. When you overfeed your fish, excess food can break down and release nutrients into the water, providing a feast for the algae.
To prevent overfeeding, make sure to only feed your fish as much as they can consume within a few minutes. You can also use a food meter or a timer to ensure that you’re not overfeeding your fish.
Insufficient Water Flow
Another common cause of brown algae is insufficient water flow. When the water in your tank is stagnant, it can create an environment that is conducive to algae growth.
To prevent brown algae, make sure to provide adequate water flow in your tank. You can achieve this by using a powerhead or a canister filter, which can help to circulate the water and prevent stagnation. (See Also: When to Change Aquarium Water? Timing is Everything)
High Nutrient Levels
High levels of nutrients in the water can also contribute to the growth of brown algae. This can be caused by a variety of factors, including:
- Excess fish waste
- Decaying plant matter
- Overuse of fertilizers
To prevent high nutrient levels, make sure to maintain good water quality in your tank. You can do this by performing regular water changes, using a high-quality filter, and avoiding the use of fertilizers.
Changes in Water Chemistry
Changes in water chemistry can also trigger the growth of brown algae. This can be caused by a variety of factors, including:
- Sudden changes in pH
- Sudden changes in temperature
- Sudden changes in water hardness
To prevent changes in water chemistry, make sure to monitor your tank’s water parameters regularly and make adjustments as needed. You can also use a water test kit to detect any changes in the water chemistry.
Preventing Brown Algae in Aquariums
Now that we’ve discussed the causes of brown algae, let’s talk about how to prevent it from growing in the first place. Here are a few tips to help you keep your aquarium algae-free:
Regular Water Changes
One of the most effective ways to prevent brown algae is to perform regular water changes. This can help to remove excess nutrients and waste products from the water, making it less conducive to algae growth.
To perform a water change, simply remove 10-20% of the tank’s water and replace it with fresh, dechlorinated water. Make sure to monitor your tank’s water parameters before and after the water change to ensure that the changes are not causing any harm to your fish or other aquatic inhabitants.

Good Water Quality
Good water quality is essential for preventing brown algae. This can be achieved by using a high-quality filter, performing regular water changes, and avoiding the use of fertilizers.
To maintain good water quality, make sure to monitor your tank’s water parameters regularly and make adjustments as needed. You can also use a water test kit to detect any changes in the water chemistry.
Adequate Water Flow
Adequate water flow is also essential for preventing brown algae. This can be achieved by using a powerhead or a canister filter, which can help to circulate the water and prevent stagnation.
To ensure adequate water flow, make sure to provide enough powerheads or canister filters for your tank’s size and type. You can also use a flow meter to monitor the water flow and make adjustments as needed.
Conclusion
Brown algae can be a frustrating problem for aquarium owners, but by understanding the causes of its growth and taking steps to prevent it, you can keep your tank looking its best. Remember to perform regular water changes, maintain good water quality, and ensure adequate water flow to prevent brown algae from growing in your aquarium.

Q: Can I use chemicals to remove brown algae from my aquarium?
A: While it may be tempting to use chemicals to remove brown algae, it’s generally not recommended. Chemicals can harm your fish and other aquatic inhabitants, and can also disrupt the balance of your tank’s ecosystem. Instead, it’s best to use physical methods, such as scraping or magnetizing, to remove the algae.
Q: How can I prevent brown algae from growing in my aquarium?
A: To prevent brown algae from growing in your aquarium, make sure to perform regular water changes, maintain good water quality, and ensure adequate water flow. You can also use a algae magnet or a algae scraper to remove any algae that does grow.
Q: Can I use plants to control brown algae in my aquarium?
A: Yes, you can use plants to control brown algae in your aquarium. Some plants, such as Anacharis or Hornwort, are particularly effective at absorbing excess nutrients and reducing algae growth. You can also use plants to provide hiding places and shelter for your fish.
Q: How often should I perform water changes to prevent brown algae from growing in my aquarium?
A: The frequency of water changes will depend on the size and type of your aquarium, as well as the number and type of fish you keep. As a general rule, it’s recommended to perform a 10-20% water change every week to 10 days to prevent brown algae from growing.
