Yes, LED light is great for your planted aquariums and plants. Without enough light, your plants create enough food for themselves through photosynthesis. However, all plants have different lighting requirement some need more than others so it’s important you chose a good LED light for your plants.

How many lumens do I need for a planted tank?

Again, this depends on which plants you have. Low light plants won’t require as much as high light plants. Here are some general recommendations;

  • Low-light: 10-20 Lumen or 1-2 watts per gallon.
  • Medium Light: 20-40 Lumen or 2-4 watts per gallon.
  • High Light: 40+ Lumen or 4-8 watts per gallon.

How long should I leave my aquarium light on?

At a minimum, you should have your lights on for at least 7-8 hours and as you start to understand how your plants react to the lighting you’ve provided you can increase the photoperiod as needed without exceeding 12hours.
