Does blue light cause algae in freshwater aquariums?
LED lights for freshwater aquariums emit a minimal amount of blue light, which is generally not a significant cause of algae growth on its own. However, prolonged exposure to intense blue light can contribute to algae problems. To prevent algae issues, it's essential to maintain a consistent lighting schedule, avoid excessive light duration, and consider using LED lights with adjustable colour spectrums to mimic natural lighting conditions.
Do I need a UV light for a freshwater aquarium?
A UV light for a freshwater aquarium is not a necessity, but it can be beneficial in certain situations. UV sterilizers or clarifiers can help control algae blooms and eliminate harmful pathogens, promoting clearer and healthier water. If you're struggling with persistent algae problems or dealing with water quality issues, a UV light can be a valuable addition to your aquarium's filtration system.
