What is actinic blue light?

Actinic Bulbs – Emit light predominantly from the blue end of the color spectrum. Recreates light conditions found in deep water and provides the light energy necessary for proper photosynthetic coral growth. Actinic bulbs are ideal for reef aquariums. Plant Bulbs – Emit light that stimulates plant growth.

What does a blue light do in an aquarium?

This is particularly good for nocturnal fish, as a dim blue light can be left on the tank to simulate moonlight and allow for feeding and viewing purposes. There are even LED lighting strips that replicate the monthly lunar cycle. You can have fun changing the light with the remote or app.

Do blue LED lights cause algae?

Blue lighting can cause excess algae in freshwater and low Kelvin lighting, peaking in the red, can encourage algae in marine aquaria. Bulbs and tubes degrade over time, lowering their Kelvin rating, possibly causing more algae and producing light less useable by plants or corals.

Do fish like blue light at night?

Nocturnal fish particularly prefer dim blue lighting at night. The blue lights not only mimic moonlight and, thus, encourage more physical activity, but these also provide them with illumination. There’s also the fact that blue light allows you, their human parent, to view them well.

Does actinic light grow coral?

Which Colour light is best for aquarium?
