Kessil Club

I'm in the process of setting up a tank that's 24" long x 12" wide x 12" deep. I'm considering running two A80s over it, so each fixture would basically cover a 12 "cube.

I know the A80 is a newer fixture, so I'm not really sure how capable it is. Has anyone used an A80 under similar circumstances? I'd love to get some feedback on what I could grow under these lights.

Less light demanding LPS and softies would work great under the A80. It's not bright enough for SPS. I'm currently testing an A80 as a refugium light. Time will tell.
 
I just switched to two Kessil 360WE's from 6 ATI T5's. The first thing I'm noticing, (and definitely is bothering me), is that it looks like it's extremely dim - at least compared to my old T5s.

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.

At what color % are you sps dominant folks getting the best color?

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.
 
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.

Why do you think that?

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.
