Obviously at the 30% I'm starting at I wasn't expecting to be blown away with brightness, but even when I just tried the 70-80% range, it was better but wasn't perfect.

My question is, I see people max running their Kessils at 50-60. I really would love to run my tank at around 75-90, at least for a few hours. Is that anyway possible? I have the two fixtures 9 inches above the water.

Also, what is the equivalent of the 6 bulb T5s I was running in terms of intensity with these Kessils? Anyone have any idea?
I get almost the same PAR with my 4 T5 bulbs compared to my 2 A360WEs at 100% intensity 25% color (140 Kessil vs 110 T5 at ~13"). I'm sure the PUR is better with the Kessils though. Kessils are 9.5" above water line and 6 inches apart.

I'm at 52 with an intensity of 72....I've been increasing intensity 2% a week until I get up to 100% intensity. I'll probably leave the color at 52 since I like the color it's currently bringing out.

25% but I recently added T5 supplementation. I wasn't having much luck with SPS coloration but that may have been because my lights were too close to the water before I added a canopy.

25% color seems very blue...

It is, and that's all corals need for the most part. The rest is for personal looks preference.

I suppose you are correct. But, I would expect growth to be quite slow at that setting.

If he's acclimating corals to a new fixture, knowing what I know now, I'd suggest starting out very low with intensity. The corals will survive lower lighting much better than burning them to death.

It's typically been stated that with more white lighting, growth is faster. With more blue lighting, growth is slower but color is more preferable.

I guess this is usually said about MH and T5 lighting, does this not hold true for LED and/or specifically Kessil?

Kessil always have the blue spectrum. You just dial in how much white you want.bb

So, how is that different than a heavy blue MH or T5 yet doesn't slow growth? I'm just trying to wrap my head around the potential differences.

Do you all run your Kessils at 25% color with good long term results? Specifically sps colors?

I don't think anyone really knows for sure the spectrums they use outside of blue. The ATI T5 bulbs all seem to have a peak in the blue spectrum. It also depends on what spectrum they were grown under initially.

Kessil will tell u that they will all grow at pretty much same interval. Mostly cosmetic. It's witch craft. That's why they don't let full control of spectrum like radeon.

Well the other spectrums are filtered out as the water gets deeper in the ocean. That's why we know they use blue.

Kessil doesn't give you full control because you're more likely to have problems from choosing a bad spectrum. That's one of the reasons why people have more challenges with LED as opposed to T5 and Metal Halide.

No, it's because MH isn't spectrum controllable - other than swapping a bulb or a ballast.

You didn't. People have a tendency to get up in arms about the choices that they make for lighting ever their recess times it's almost as if it's brand loyalty sometimes. I happen to believe it it's a matter of personal preference that if the light fixture itself is designed to produce the spectrum the corals need for health then you're good when it comes to Castle they have locked in the blue spectrums so that we don't have to fool with it

I run a Kessil, have for 2+ years and have no complaints. I'm simply trying to further my understanding of it all. I see a lot of mixed opinions on the Kessil (well, and every other light, haha.) so want to try to fully understand for my own peace of mind.

I get that you're saying all reef light is in the blue spectrum. I guess maybe I'm equating the 25% color to say...running all blue+ or actinic bulbs in a T5 fixture. Not many people do that, in order to achieve a fuller spectrum reportedly. So that's probably where my struggle is to comprehend the possibility of decent growth rate at that percentage.

You follow where I'm coming from?

I would say it is less blue than all blue+ but I don't know what it would be compared to something else. Maybe closer to 20k?

I can't really comment on growth at different spectrums except that my hammer coral is growing faster since I added T5s, which may be from spectrum, intensity or better diffusion.

It would seem there's probably some intensity/PAR lost running at a low color percentage. At least to my eye when I try 25% color vs say 50% color.

It is a very small difference , I asked someone to test for me and was surprised by the results. Your eye is very poorly calibrated to test par and is many more times sensitive to the green in the cool white leds in the white channel. Human eyes work more like lux meters.

Doesn't really matter. The PUR is higher. Our eyes are bad at seeing the blue spectrum. Best with green. Also, I wouldn't change your color % rapidly. Your coral probably won't like it.
