Has this happened to anyone (Kessil White Spectrum Burn?)
Has this happened to anyone?
I been led to believe that the Kessil's spectrum logic takes care of Color/Intensity mixing, thus the only thing to be concerned about when adjusting Kessil is the Intensity, not the spectrum.
Yes, changing Intensity too quickly can have drastic consequences. I've learned that lesson with my light sensitive corals.
I've spent months slowly tuning my Kessil to keep my Acans/Zoa's happy while keeping other LPS in check. I pretty well stopped at 60% intensity, after going over this level and having to back off.
So a few days ago, I turned my Spectrum to 100% to take a picture, and forgot to change the Apex Spectrum setting back to auto. Intensity continued as programed.
What caught my attention was this. One of my Torches branches lost it's color.
The tank has the Kessil in the middle of my tank, with 4 T5's across the tank.
There is a large Leather that has grown so much it shadows half the torch from the Kessil.
So is it possible the drastic shift from Kessil 0% spectrum to 100% spectrum at 60% intensity (my max) did this?
There is another clue, since I know my Acan's are particularity sensitive to lighting changes, and as show below, the Acan of the further left of the Kessil hasn't been affected, but the Acan closer to the kessil has been affected.
So it appears the Spectrum swing on a Kessil can have an affect.

With over a year of using the Kessils, they are my favorite of any of the lights I have ever used. I also keep the color at a max of 60% (on the blue side) and the tank aesthetic has never been better. Also strong growth and coloration of most corals. About the only issue has been shading, so I ended up with more lights than I had anticipated (a mix of 360 and 160 over my 265). I do still run my reefbreeders line source lights.
Interestingly, my torch is 'pale' like the prior post notes - yet is has grown from just two heads to 15 and its huge. I think the paleness may be a consequence of higher light and less need for zooanthele. My torch is also in the path of my tank feeding so it catches a lot of food.

Kinda different but I noticed my 350's are much bluer then my 360's the 360's have a purple tint to them. I prefer the 350's for this reason. My corals respond very well to the 350's
I really like that, they just sit in there?
Only one suggestion comes to mind, and that's put the piece of wood on top of the metal L's rather than below, and use locknuts on the bolts instead of plain 'ol nuts. Just call me paranoid, though!

Not sure what 100% spectrum you mean? Blue or white?
The difference could be the energy of the light. White light carries more energy than blue on the RF wavelength. So your intensity setting may not have changed but if your running white 100% then it would have more energy than blue at the same setting. Make sense?

Kessil told me to reverse the brackets connecting to the tank, and this worked perfect.

I believe that is what the "Kessil Logic" is supposed to circumvent but not positive.

It's an allen head screw. I take my A36owe's apart several times a year for cleaning. Take your time and don't force anything.

Thanks, Home Depot didn't carry anything that small. I found an allen wrench that fit at Lowes. It was part of an electronics kit and was size .9 I don't know if they can make anything smaller.

Hey guys!
I have a thread going on in the sps forum for lighting suggestions, please pop on over there, or chime in here.

which kessils and how many would you all recommend for lighting a 8' x 30W x 24"H peninsula display?

Finally found a decent white balance on the S7.
Looking good!

In this installation, the white blocks are not even used.
Hi everyone.
Given my tank is only 16" in depth, how high should I mount my A360WE above the water surface? Currently I set the light in 65% color and 5% intensity. 6" above the water. The light is super bright and shines beautifully on every corals. My tank is mainly for LPS. I am a newbie to Kessil.
Thx

hey guys,
on an 8' long tank, 30"W x 24"H peninsula, I would think 2 rows of 3, or 2 rows of 4...
but how high above the waterline should I mount them for coverage?

I have them mounted 4.75" above the water and they easily cover beyond the 18" width of my standard 75g.

40b. 2 a160WE about 9" off the water. Had my friend who works at a metal shop bend 90° Metal arms to hang them from, powder coated them. I run a 14 hour schedule with a slow ramp from 6am to 1pm peaking out at 85 intensity and 70 color then from 4pm to 8pm a ramp back down.
