Your chalices are great. I wasn't referring to you I meant in general for people who have been having troubles

what's wrong with my chalices?

Not quite done with the build yet, but will be running some 420 on their own dimmable channel. It adds alot more pop to the array than just RB/CW. I have some chalices so well see what happens. Having personally seen a strictly LPS/Z&P tank under LED with rich coloring, i think most people are running their LEDs too high,wrong color combo, water quality issues or a combo of the three.Is anyone keeping chalices under a DIY fixture that incorporates some True Violet 420nm LED's? I wonder if that would help.
I think Reefledlights' chalice photos speak for themselves in this thread.They run strictly RB/ CW i believe.The coloring on those chalices is super rich which just further illustrates that anyone having issues with fading is due to other factors than LEDs themselves.Mixing in others such as red, true violet etc is mainly for aesthetics.Now that I've seen the true violets combined with the daylights, RB's etc I can't imagine not running TV in any future builds. But they aren't there for growthI thought white LEDs incorperated the full spectrum of light, and the blue color made them pop. Whats the science behind wanting different colors other than for asthetics. I am going to get a dimmer for the LEDs, and probably go 50/50, cree blue and whites. IS that bad? Remember its only for LPS, mainly chalices.
Thanks
He still didnt say what LEDs he uses (brand), or how long they have been under there, or what intensity he is using. There has to be some correlation to the poor results of so many other than bad water parameters. I am trying to figure out if its intesity, or time or brand or color diversity or what, so I dont spend the $$ and hurt my corals, and I do it right the first time.
Great stuff guys, thanks for the info. I am unsure what the premium bin LEDs are though. I am looking at Cree LEDs, are those premium bins? Also, what intensity do you start at with chalices at 20" depth? And how slowly do you increase the intensity. I am glad there are successfu people out there, as I really want to go to LEDs.
Thanks,

Right on, if you can't dim remove the optics from the whites and that will reduce the "white" spectrum quite a bit and add a more "20k" look. I had my chalices under a 250W Radium running an HQI ballast before converting so I didn't see any fading except a bit on my Tyree pink WM but the rest look better IMO. Anxious to try out my UV LEDs this weekend as well to push into the 400-420 nm spectrum.My experience in a 18 inch tank, i have my cree cw/rb from reefledlights premium bin, drivers set at 950mah then tuned down with my apex, 55 percent intensity on white and 80 percent on blue. I fried a bunch of lps before finding that spot..... and still adjusting intensity since September. I removed the optics and it hangs 4-5 inches over the tank.

Aren't true " UV" LEDs super expensive, like 50 bucks per diode, and more along 375nm? From what I remember LED Engin has them
