Help with lights

[kajirae]

Hello everyone!
I’m really new to reef tanks, I’ve just swapped over from freshwater aquariums, and i have a really dumb question.
I’m running a giesseman 1x150w white for a cube tank, 45x45cm, which it s pretty nice but I rlly like that pop which you get from blue light and i m looking for a way to either complement the lights that i currently have with some blue LED s (i saw some pretty nice lights from tunze) or a way to transform the with light into blue light (ie passing the light trough a blue glass or simply painting the lamp s glass with a thin layer of blue)

What kelvin is your bulb? 6500k is the lowest and the whitest. I personally prefer 14k, but they were out of stock so now I use the 20k, which is the higher and the bluest.

For my 150w system I use 2 x orphek OR3 bars as supplement, I only have them running in the evening.

I think it’s 20k, but it’s full white

ya to me too it looks white lol.

But I can say that going from the 14k to the 20k, I did see the difference at first for a few days. But I guess my eyes have acclimated it just looks white now.

The thing is i like the blue lighting and I’m thinking of either buying a blue bulb (but i don’t want to lose any par for my corals, i don’t know if it’s the same characteristics as the one i have) or getting a set of blue LEDs and run the simultaneously to make the fluorescence pop


Another option would be to run the white lights for coral growth for 7hrs (11:30-18:30) like I do now and just turn on blue lights for a few hours after purely for display purposes

Thats exactly what I do, the MH runs during the day while I work. It runs from 9:30am to 7pm (9.5 hours), the orpheks run from 6 pm to 10pm for viewing pleasure.

I've also seen them but never tried them. Let me know if you, would like to know what they look like.

Does this not disturb the corals or fish?

What do you mean lose par? Remember the way humans see light has nothing to with par output. A blue light will look dimmer but may have the same or more useful par for the coral

Noted. So switching to a blue-light bulb would not affect my corals whatsoever. Also is it recommended to run something to simulate moonlight or just 8hrs/day of light are enough?

I run T5 six bulb. I have 4 blue+ bulbs 1 true actinic which the human eye can hardly see compared to white light, and one coral+ for my white light. It is just off and on. I run 12 hours light 12 hours full dark. Everything else is fluff.

The picture looks bluer then it really is in person
