Frequently Asked Questions (FAQs)

1. What color light is best for fish tank?

Red, blue and green LEDs are in popular use for standard aquarium lighting since these light temperatures greatly enhance the colors of the objects inside the aquarium. The colors of aquatic plants appear much more rich and vibrant, red fish, shrimp and of course red-leaved stem plants look much flashier.

2. What type of light is best for freshwater aquarium?

Your best lighting options for freshwater tanks are standard fluorescent bulbs, compact fluorescent bulbs, metal halide lights, and LED lights. You want to avoid incandescent bulbs as they are suitable only for small aquariums and can give off too much heat.

3. How long should aquarium lights be on?

How long should I keep my aquarium lights on? To provide animals and plants the lighting they need, 10 to 12 hours a day is sufficient. Installing a timer or purchasing a unit with integrated timing can make lighting easier––just set it and forget it. Keep in mind algae loves light as well.

4. How long should aquarium LED lights be on?

Most planted aquariums do not need more than 8 hours of light. Setting your lighting period for longer than 6 hours in NEW planted aquarium set-ups. During the first month your lighting period should be shorter to keep away algae while your plants grow in.
