Common types of aquarium algae
Are you familiar with the different types of algae that can commonly grow in freshwater aquariums?
These include Green Spot Algae, Blue-green Algae, Green Dust Algae, Fuzz Algae, and Hair/Thread Algae.
Let’s take a look at each of these algae and discuss how to identify them and what conditions they need to thrive.
Brown Algae in Aquariums
Brown algae, scientifically known as diatoms, are a common sight in many new and established aquariums. This type of algae typically presents as a thin, brownish layer, which can sometimes appear more yellowish or dark brown, often forming on the substrate, decorations, and glass surfaces of the tank.
Characteristics and Causes
Brown algae develop primarily due to high levels of silicates and nitrates in the water. New aquariums are particularly susceptible as they are still undergoing the initial cycling process, where beneficial bacteria colonies are yet to be fully established. Factors such as insufficient lighting, overfeeding, and lack of regular maintenance can also contribute to the proliferation of brown algae.
Identification
Identifying brown algae is relatively straightforward. It has a distinct slimy texture and is easily dislodged from surfaces. Unlike green algae, it does not thrive in well-lit conditions and tends to grow more abundantly in areas with lower light.
Prevention and Treatment
Effective ways to prevent and treat brown algae include:
- Regular Maintenance: Conducting regular water changes and cleaning the tank can significantly reduce the nutrients that algae feed on.
- Improving Lighting: Ensuring adequate lighting can inhibit the growth of brown algae.
