Aquarium blue light at night.

They are a great addition to any tank as they don t affect the day and night cycle of the fish or plants and don t contribute to the growth of algae. A moonlight typically features several tiny led bulbs that produce a blue ambient light throughout your tank. Lights with a lower kelvin rating e g. If its an actinic bulb and its a freshwater aquarium you can run it for a couple hours after your main lights turn off.

If its a marine tank it s best to run the blue lights with the white lights to provide all spectrum of lighting all at once. Whether tis nobler to give your fish a bit of darkness in the evenings or risk stressing them out with a perpetually lit tank. I would not advice them to be on all night as the fish do need to rest and in the wild the moon would move round so they would not get moonlight all night plus think of your electric bill. If you want a night lunar light that will make your fluorescent fish glow 445 nanometer royal blue lights are popular.

A blue ambient light in an aquarium is meant to mimic moonlight. It s not very bright either it kind of just has a glow to it. Blue light allows the nocturnal fish to be seen doing what they do best when the lights go out. I don t think i would leave it on permanent as the active fish during the day stay active as well.

My tanks have a 2 hour blue light faze before the light goes out totaly. There are even arrays with different colors of led lights you can program for your needs. So mine are set to come on at about 10 00pm and my daylight bulbs go off at 10 05. My aquarium came with a white day light and a blue night light.

To keep the aquarium light on all night or not to keep the aquarium light on all night that is the question. Seriously though if there s one you don t want to do it s stress out your fish. Moonlights don t affect the night and day cycle of your fish coral or plants and they don t contribute to algae growth.

I have heard some say that it s okay and some say its not okay but if the factory made it with the blue night light doesn t that mean that it would be okay for the fish. The 12k white and magenta combination can be perfect for planted aquariums.
