all Royal Blue LED for reef

[youngfish]

hi, I want to keep zoa, starpoly and scoly in a nano. To increase the look of the aquarium, I would like to go with Royal Blue only LED lighting without any whites. Will it work? Will the light good for the coral survival/growth?

I really like the look of corals under pure blue light. As long as the white is lighted up, the look is no long as good as pure blue light. But I do have concerns over the health of the corals.

yeah, they will survive just fine, not sure if they will grow as fast without some white light though. I say build a light fixture with minimal white and keep them off, if you notice the growth being too slow, slowly ramp up your whites, you can have whites and have the blues over power it. all of this is just guessing on my part, as I have not tried it yet. but some of my LFS keep corals under RB's only for presentation.

You should get a mixture of blues. 420 450 470. Cutter sells them on a tri-star. Some colors might eventually change from what they were when they grew under regular lights. Another idea: run whites when you are not home.

why not buy as unit with both white and blue, adjust you your liking. you might like all blue this week, grow tired of the look next week. at least give yourself options down the road.

All blue will work great, it is what I will use on my future frag tanks, with the addition of some cyan and a tiny hint of red to help bring out additional color with out needing any of the whites.

The cutter tri-stars are nice but kind of pricey not counting shipping. They don't use the most efficient or powerful chip bins either. If space isn't an issue just use single emitter stars for all your royal blue and violet wavelengths. Consider using a True Blue, Cyan, and Red addressable tri-star for color fill, you could use individual chips but the tri-star will blend those colors better. Steves LEDs sells those reasonably priced, non addressable version is also know as the Ocean Coral White and gives a white-ish look without being white. Either way you would not need many of them for your application.

I don't know. Add a few whites, or at least 660nm red, amber, cyan, and cool blue.
Cutter stars are too expensive, +1. Steve's Leds sells custom 3ups for the Rebel ES for only $11 reflowed.
