Frequently Asked Questions (FAQs)
1. What is the best lighting for a tropical fish tank?
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.
2. 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.
3. Which light is best for aquarium plants?
The most common form of aquarium lighting is T8 and T5 florescent bulbs. Both are capable of growing plants, however T5's are recommended. T5 bulbs are more powerful, and better suited to growing aquarium plants in a densely planted setup. One full length T5 bulb is often enough to grow most aquarium plants.
4. Is LED light good for fish tank?
How Lighting Affects Fish. Fish are not as reliant on light as plants. In general, aquarium owners can use incandescent, fluorescent, or LED lights for fish but should be aware of the heat issues that incandescent lights cause.
