Getting rid of algae in your planted aquarium requires a two-pronged approach: manual removal and addressing the underlying cause.
Manual Removal: The First Step
The most immediate way to tackle algae is by physically removing it.
- The best treatment is to manually remove it with a glass-safe aquarium sponge.
- Alternatively, you can use a clean razor blade, taking care to avoid scratching the glass.
Regular manual removal prevents algae from spreading and makes the subsequent steps more effective.
Addressing the Root Cause: Nutrient Imbalance
Simply removing algae won't stop it from coming back if the conditions that caused it persist. Algae growth generally stems from an excess of phosphates and other organics. Therefore, it is crucial to treat the cause of this nutrient imbalance while performing manual removal.
Possible steps to address excess nutrients include:
- Performing regular water changes to dilute nutrient levels.
- Ensuring you are not overfeeding your fish.
- Considering if you are using too much fertilizer for your plants relative to their uptake.
Evaluate Lighting
Another significant factor contributing to algae growth is lighting. Strong lighting in one area can cause it to be especially bad.
- Evaluate the intensity and duration of your aquarium lights.
- Consider if certain areas are receiving disproportionately strong light.
- Reducing the total light duration or intensity can often help curb algae growth.
By combining consistent manual removal with efforts to balance nutrients and optimize lighting, you can effectively get rid of algae and maintain a healthy planted aquarium.
