Frequently Asked Questions (FAQs)

1. Can I use plant grow light for aquarium?

Can I use a grow light for aquarium? If you have a look at different spectrum of the light emitted by one LED fixture from grow Lighting UK, this flat linear lighting is far more efficient than HPS or CFL lamps. So yes!

2. What kind of light do I need for a planted aquarium?

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.

3. What color light is best for plant growth in aquarium?

Warm white LEDs often work better for growing plants, however, they cast a yellowish visual tone on the tank as they lack adequate blue spectrum.
