Cause Of Brown Algae In Aquarium
It is common for aquarium owners to encounter brown algae in their tanks. Brown algae are not really algae, they are a type of bacteria called diatoms. They are usually harmless but can be unsightly and can compete with other organisms in the tank for nutrients. In this article, we will discuss the causes of brown algae in aquariums and how to get rid of them.
High Nutrient Levels
High levels of nutrients in the water can promote the growth of brown algae. These nutrients come from uneaten food, fish waste, and decaying plant matter. Overfeeding your fish can also contribute to high nutrient levels in the water. To prevent this, make sure to feed your fish only the amount of food they can consume in a few minutes and do regular water changes to remove excess nutrients.
Low Light Intensity
Diatoms thrive in low light conditions. If your aquarium is not receiving enough light, brown algae can start to grow. Make sure your aquarium is receiving adequate light for the type of plants and organisms in the tank. If you have live plants in your tank, they require a certain amount of light to survive and will compete with brown algae for nutrients.
High Silicate Levels
Silicates are naturally occurring minerals that can be found in tap water. High levels of silicates in the water can promote the growth of brown algae. To prevent this, use a water conditioner that removes silicates before adding tap water to your aquarium. You can also use reverse osmosis water, which has very low levels of silicates.
Low Water Flow
Brown algae thrive in stagnant water. If your aquarium has low water flow, the water may become stagnant and promote the growth of brown algae. Make sure to have a filter that is appropriate for the size of your tank and regularly clean it to ensure proper water flow. You can also add a powerhead or air stone to increase water flow.
Conclusion
While brown algae may be unsightly, they are usually harmless to fish and other organisms in the tank. By addressing the causes of brown algae, you can prevent their growth and maintain a clean and healthy aquarium. Remember to control nutrient levels, provide adequate light, remove silicates, and maintain proper water flow.
