Over a year of use now with 4x Hydra26 & 2xHydra52 over my 84x40x30. Very happy with the lights and the colors I'm getting.

The white channel is stronger than the 2 blue channels combined. I run my whites at 85 and blues at 100. The whites put out more power at 85 than the blues together at 100. To get approximately equal output the whites would need to be at 71 and both blues at 100.
FYI - I have a spread sheet and did some basic testing to verify the sheet.
The whites are the strongest and have more diodes than any other channel, so take your time bringing them up in power.
My tank is rather white in appearance.

Very nice what do your settings look like
Thanks. My graph is below:

Hi all - I have a Hydra 26 coming in the mail tomorrow, and wondering if it's enough for my 40 gal cube (23x23x18) with LPS and RBTA after reading this thread.
I currently have a DIY LED build: 12 Cree XPE whites and 24 XPE blues (3 watts each - 108 watts total) with 3 non-dimmable drivers. I feel like it's burning my corals even at 24" above the water, getting fading colors on my LPS...
What % should I start the hydra on, and what should I acclimate it to over what time period? Thanks!

Thanks! I did the timer (easy) setup and have similar settings except UV is low - I noticed most people keep UV around 10%. I am running from 10am-10pm with 2hr ramp. Does that sound about right?
One thing I didn't understand was the favor white/blue, and the transition left to right/right to left/uniform. Anyone have any guidance there?

Nice work Wazzel, here is my first schedule a month ago and also my current schedule, plan to increase the first 4 channels to 100 with in the next few weeks. Very impressed at to the coral reactions and response from these fixtures.
Regarding the white channel, I've seen first hand of local professional coral seller who run his white channels for 2 hours only at max of 30 percent with absolutely amazing results not just color but growth! According to him, the other blue/uv/pink are pretty much all you need to have good color and good growth. Normally any one would disagree though I was amazing at his results and I've been just about everyone and seen tons of successful tanks all around.
I guess it would depend on the specific set up. Since colored LEDs produce narrow bands of light I would be concerned with not running a broad spectrum white to fill in the gaps.
Here is a little study I did last year, you may find helpful.

Quickly looking over your thread I admittedly didn't want to focus on your data since its based off par which we really can not use for led's its a data number in which can not be shared between fixtures and setups for different systems since it would be a standard recipe for success. There was a study based on just blue led's (forget which wave length) that grow coral similar in growth as full spectrum etc... I personally believe white is important but mostly for human visual viewing. Would be interesting to see your coral color different if you dropped your white intensity or duration on your system.
