Buy aquarium LEDs for beginners
Have you just set up your first aquarium and are looking for the right lighting? Here you'll find simple, affordable LED light bars that are sufficient for most freshwater aquariums – without having to spend hours poring over wattage and light spectra.
What you really need to know as a beginner
For a typical freshwater aquarium with plants, you don't need expensive professional equipment. The only important rule is this: the light should contain both blue and red wavelengths – plants use these for photosynthesis. As a general guideline, you need about 0.3 to 0.5 watts of LED power per liter of aquarium water, depending on the needs of your plants.
What you really need as a beginner - Too little light: Plants barely grow, the tank appears dull and lifeless
- Too much or the wrong spectrum: Algae proliferate
- The right light: Healthy plant growth, vibrant fish colors, clear water
