How To Choose LED Lights For An Aquarium?

Consider the following factors before choosing the right LED.

  • Plant and fish needs

Proper lighting helps you see the activities of the fishes and help the fishes thrive. Lakes, rivers, and seas have natural daylight, and LEDs mimic the natural lighting. Also, plants require light for their organic growth. LEDs provide various artificial nutrients that help stimulate plants’ growth.

  • Spectrum and intensity of the light

The intensity and spectrum of the light not only make you change the décor of your aquarium, but also add life to it. Spectrum refers to a mixture of different colors, while the intensity of the light refers to its brightness. Lights with higher intensity can promote the growth of algae, whereas the spectrum can add different color effects to your aquarium, affecting the temperature and the survival of plants and fishes.

  • Size

The size of the tank is a significant factor to consider while choosing the perfect light. Larger and deeper tanks require lights with higher intensity, whereas smaller tanks require soft light.
