Why do people like the "blue" look?

Why do people like the blue look on their tanks? I'm one who prefers more of the white light so I can actually SEE my tanks inhabitants and whatnot. I like the blue look at night for lunar light.

Why does one person like say Honda cars and another likes ford trucks. Everyone is different and that's what makes life great

Yeah. Different strokes. I like blue when it's night time. Corals look great to look at.

It is easy and fast to see "results," even if they area mostly artificial. "Glamour Shots" for corals... if any of you go back to at time when somebody wanted to set you up with a friend of theirs and showed you a "glamor shot" that you knew that they would be 75% uglier in person.

The blue light shows the flourescense is corals better. I like my tank pretty "white" during mid day, but in the evening when I'm relaxing and looking at the tank I prefer the "blueish" look as it seems to showcase the colors of the corals.

I don't like the full washed out blue look, rather I prefer a 14kish look, which is white and blue mixed, but not too blue.

During the day my tank is a cool white, you probably wouldn't even know the blue leds are even on. But for a couple of hours in the morning and again in the evening, I like the all blue tank. If you have corals and anemones that fluoresce, it looks like Pandora (the movie Avatar) at night when everything 'lights up' and the colors just 'jump out at you'! But then about 75% of the corals and anemones in my tank fluoresce Yes, it's totally artificial looking, but at the same time, these are living animals that can look like such an alien world. I just think it looks very cool. Especially then the house is dark and it's dark outside so there is no 'daylight' coming in the windows. It's kind of a deep ocean, bio-luminescence look, even though that's not what is going on at all.

I prefer the warmer tone around 6000-8000K, with the blues off, but I found out that the algae seem to have the same opinion.

I guess the blue look goes with a "modern" aesthetic, clean lines, sterile and high contrast.

I think it depends on what you mean by 'blue'. Ocean water rapidly filters out the red end of the light spectrum, so the use of actinics and now blue led was about adjusting aquarium light for this shift (none of our tanks are tall enough to do this the way nature does). Depending upon the depth one is trying to replicate, anything between about 10 and 17K is normal. Beyond that it's simply an aesthetic preference or disingenuous attempts to distort the appearance of a coral.

I know what he means, black light poster tanks that seem all the rage lately, not a fan, I prefer a 12-14k look most of the time w/ blue moons at night, but the all blue main lights don't do it for me, and I see people asking for ID's or does this nem/coral look ok and I all I see is variations of blue and can't even see details of the animals, but to each their own...

Yeah, the "windex" look is all the rage indeed. As a diver, and as ca1ore posted, the reefs are somewhat blue, but definitely not as blue as the windex look. I, myself do what others have posted, daylight during the day and blue in the morning and at night.

The reason that everyone uses the blue, at least to us older reefers, is science and books (before the modern internet). It is that out in the ocean where most of/not all of the coral we have in our tanks, are living, somewhere between 15-20 meters. At that depth, most of the available light that reaches them is within the Blue spectrum. Saltwater and Light spectrum 101: When the sunlight hits the surface of saltwater and penetrates the surface, this is what happens; Red and orange are the first to go, after about 1-3 to meters. Then the yellow and then green at about 10-20 meters then purple and finally blue. Now there are people that have recorded awesome growth with 6500K lighting but the coloration was off so to speak. This is why, we as aquarist, attempt to give our corals an emulated natural light source, one that is natural to them and their natural environment which may not appeal to our individual aesthetics. Also, how the florescent proteins in the zooxanthellae react more toward the blue spectrum is a bonus for us reefers! Hope this helps!
