How many Violet LEDs to get actinic effect?

[Stlouphil]

I'm running 2 - 250watt Radiums and added 6 - 12 watt Royal Blue Luxeon Ms to supplement blue and add additional pop. Question: How many violet LEDs would I have to add to get a noticeable additional actinic pop with the Radiums and Luxeons already in place?

Highly subjective obviously and dictated by many factors.
Throw a few at it and see if you are personally happy.. if not add a few more.

4 million.

That should help with your tan too. (Tagging along.)

4 million? I would have to change my I hate LEDs stance. Oh, I have. Never mind. :lol2:

Depends how youre laying them out. A good mix of 460nm, 430nm, 420nm and a 400-410nm should cover the entire actinic spectrum. Sometimes those ranges are hard to find. But try to vary the colors.

If you add enough to be noticed with 250W radiums on, you will probably kill your corals in a day or two.

Hey. Thanks for the helpful and insightful reply. : /

your welcome, but remember not to over power the corals. We often run too much electricity through the actinic lights because our eyes can't perseve the blue spectrum as well as the green, yellow & red. so acclimate slowly and have a dimmer attached if you can.

Ahmed your post WAS helpful and insightful. My comment and the sarcastic : / was suppose to be posted to the snide remark about killing my corals in a day or two! Stupid IPhone!

Anyways, Yes I fully understand that the visual effect is more difficult to perceive with the violets. Acclimation on my current RB's that I added is being achieved by duration of photo period until I decide on a controller.

Again, Ahmed your post WAS helpful and insightful. Thanks!

you're welcome. sorry I didn't pick up on the sarcasm. good luck. Tell us how it goes.

I'm doing the same. I have 3 x 400W MH and I'm adding 2 x 200W blue (450nm)/violet (410nm) to add a color.

My surface is 34" x 96". I'm still setting it up so I can't tell you how it'll look live but the color improvement is dramatic with the LEDs

Here is some photos of Royal Blues up and running on my 90 gal. This is also the thread that inspired me to add RB led's.

That's why I combined RB 450nm with near UV 410nm

I toyed with sub 400.. 380, 360 but decided it was a little too risky

below 400nm is risky. High amounts of UV would not just damage to corals but all the micro organisms that live near the surface if the water. halides tend to output a slight amount of UV anyways.
