    Hey Guys,

    I recently designed a LED panel for my pico reef i'm setting up.

    The light looks like this:

    i would drop 2 UV as for a pico thats overkill
    rather at 2 x 10k
    or 1 x 10k and 1 royal blue

    Personally I would be happier with a couple more 10k whites in there.

    Hmmm, seems I may have made a few mistakes with this light :/ and I've already made it (Curse only finding this forum now).

    Will this light still be effective enough to grow some mushrooms, zoas etc or have i made something unusable?

    Any pics over the tank filled with water and some rock, would also help with choosing the right color spectrum you want.

    I know the first color to fade is blue when hitting the water

    From what I read recently it seems that Blue is the most effective for coral growth as it penetrates to levels where the coral is usually found in nature. More effective than white even.

    So does that mean you should have a higher compliment of blue compared to other colors or should there be a balance between all colors.

    Maybe someone has a guideline, for example:

    LED spread should be:
    50% Blue
    40% white
    5% red
    5% green

    remember we as reefers influence how the light looks for our own viewing, too blue and we get better colouring but doesnt appeal to us, to much yellow, better growth but water looks like pee, its about finding a balance

    Sure, but a balance like I have shown of Blue and White (the dominant colors) should be pretty ok .... no ?

    The trend lately is a ratio of 2:1 Blue/White.

    So, two blues for every white.
    The UV range is also very important, from 390nm to 420nm.
    Cyan at 490nm is also quite beneficial.

    I would forgo red and orange, they don't penetrate very far into the water and your whites should provide enough of the lower end of the spectrum anyway.

    Nice build.
