Can anyone with experience with the Neptune Sky provide feedback on my current schedule? I have 3 Sky lights over a 6x2x2 mixed reef and would like to hear other's opinions before I start adding more expensive sps to the tank.

This is an existing reef that is about a 15 months old. I have had the lights since September and this is the first time I am adjusting the schedule as the previous did not have the look I wanted. Mostly frags with a few decent sized euphilia in the lower 1/3 of the tank.Is this an existing reef?
Replacing / switching lights?
New reef?
What size corals are we talking about (frags vs colony)?
Personally speaking as an owner of SKYS for almost a year now I do not bounce between presets. I'm not sure why you are doing that. I run two SKY's over a 210 54 x 30 x 30 system. 80% of the day I'm using 'coral growth' which is 100% across all channels with a peak power of 80%. I ramp up at 0700 and lights are off at 2200. The last 4 hours of my schedule I am running PHX14 I think it is.
I've measured PAR at 3 locations in my display using each of the SKY's preset spectrums. At the same time I did that I also adjusted the brightness percentage (power) so now I knew PAR per spectrum and brightness. This helped me get an idea or calculate DLI if I so choose.
Since I swapped from Kessil a360x I could compare and acclimate over time.
I have a PAR meter and will get the readings later today to confirm the intensity.So you have the Neptune PMK or a PAR meter to check your PAR? That's really the only way to know.

Thanks for the feedback.
Time | Point | Violet | Blue | Amber | White |
7:00 | 0 | 50 | 25 | 0 | 0 |
10:00 | 100 | 100 | 50 | 10 | 10 |
12:00 | 100 | 100 | 40 | 30 | 30 |
18:00 | 100 | 100 | 50 | 10 | 10 |
20:30 | 100 | 50 | 25 | 0 | 0 |
22:00 | 0 | 50 | 25 | 0 | 0 |
Thanks for this. Going to try this for a while and see how things go.I normally shoot for 8-10 hours of steady par with 1-2 hour ramps.
I would suggest this:
8:00, All Blue, 0%
10:00, AB+ (or SKY), 50%
14:00, SKY (or Coral growth if you want more white), 45%
18:00, AB+ (or SKY), 50%
20:00, All Blue, 25%
22:00, All Blue, off
That will give a nice blue viewing in the morning and evening with some white for color development in the middle of the day. You could use the SKY setting from 10:00-18:00. AB+ is a little bluer, SKY is slightly blue and coral growth is a nice white. In terms of PAR at the same point intensity, Coral Growth > SKY > AB+ because of diode usage.
How long have you ran Sky's for? I've had zero luck with my Sky's so far, for getting my sps to take off. Like my previous t5 hybrid fixture did.Another option I am playing with right now is to boost the violet channel to broaden the 400-500 peak. My thought is that the violet may help to color up my sps a little more. Since I was running the point intensity at 50% before, I get 50% more violet. In this case you would do something like this:
Time Point Violet Blue Amber White 7:00 0 50 25 0 0 10:00 100 100 50 10 10 12:00 100 100 40 30 30 18:00 100 100 50 10 10 20:30 100 50 25 0 0 22:00 0 50 25 0 0
Here are some calculated spectra:
I did some par measurements and the violet:blue par ratio is ~1:2 for the mod blue, which aligns well with the above. Overall par of the 3 above settings is similar.
I just looked through your build thread. I don't think the light is your limiting factor. Since you replaced all of the rock, sand, plumbing.... I think you are just in that stabilization phase. Could be a few more months before it is ready for SPS.How long have you ran Sky's for? I've had zero luck with my Sky's so far, for getting my sps to take off. Like my previous t5 hybrid fixture did.
