The shimmer really adds that special touch. Now for the question, I like my tank on the blue side, also for the corals to pop. I have mine at 65% intensity, and 25% color. Question is , is the 25% blue ok for sps ? I know they have the Kessil Logic, so am I safe running at 25% color.
Thanks here is a pic..

Beautiful tank....congrats on joining the Kessil Club!! The SPS currently in my tank are a pink birdsnest, Yellow Stylo, and a GARF Bonsai. I have read guys pushing the color upwards of like 45-60. For the deep water Acros like my GARF, I can go no higher than 40 color on my tank before they start to bleach them. I think if you stay between like 25-40, you will be ok.

Guys I have a question, I know when you add LEDs you have to slowly ramp up to avoid scorching your corals. So my question is, how do you know what intensity to stop at? When the corals seem to grow well? When it looks good to your eye?

Unfortunately, the chart does not cover the standard 29 gal. AGA which is a 30" front/length.

[rblackdvm]

At 30" you'll need at least two of the wide lights. They have a 24" spread.

Thanks. I have an a150 now on the tank and an a160we that is on the way. I wish I had 2 of the 160's so I could control both.

Anyone have an issue with the Kessil Controller display? My controller works, but the display goes blank, Kessil indicated that it was an issue with the cord or the USB converter, so i tried several other generic cords and converters and it seems to work for a short period of time ultimately blanks out and won't wake up again...

So the color is the limiting factor with these light, not the intensity? Interesting....`

As of now i have x2 d120 led fixtures over my 75g dt sps dominate with lps and zoas and palys on the sand bed. They are doing ok but i was thinking about getting x2 a360w-e wide lens instead are these more then enough for what i have?

[rblackdvm]

2 a360we should be enough. It takes corals upwards of a month to get used to Kessils, but once they do you'll see the difference.

[yukimika]

Just got two kessil 360we for my 90 gal. coming from t5andMH mix. Loving it so far. I didn't do any acclimation period, maybe just hung them a little higher. Loving it so far, was a little hard to get used to all the dancing lights at first. I've noticed my corals showing much better polyp extension and starting to pop a lot more. also noticed my corals that used to grow vertical have started to expand out, like they are not reaching for light anymore

You stop and back up a bit when you see adverse reactions from the corals. This is why you want to increase the intensity very slowly. I suggest no more than 5% a month and spread it out once a week so you are only increaseing a slight amount each week. When you see an adverse reaction, back off 5% or quit when you see your corals growing nicely. It does take time for the corals to adjust to the lighting though so increasing 1% or so a week is the safest method IMO and just watch for an adverse reaction.

Ok I understand. So what do you do if your constantly adding corals? I feel like you're never going to be as bright at you want because your constantly acclimating.

Acclimate them on the bottom of the tank and or off to the sides of the tank as you would with any other corals under high intensity lighting.

does anyone having any trouble with zoas not opening under kessils,I have the zoas on sand bed and kessil a360we 10" above tank and they do not open,when i bought them they where out fully,is the uv kessil uses the issue,I have intensity at 70%.tank is 26 inch high.I can't imagine the intensity causing a issue at that depth.color is 35-40 more%.any ideas getting very frustrated with kessils and finding the sweet spot.I have had these lights for five months and started at 30% intensity so i went up very slow.I just don't understand it.other corals and bubble tip nem are doing good,some lps,sps that i had bleached and they were mid way down tank.so some corals are ok and others not so good.

What was your lighting before hand. It took me months to get to 85% intensity. I started at 45. I have a 20 gallon long,with my kessil 12 in above water line. My zoas are not directly under my light though more towards the left.

[heliguy71]

i was using 120watt china leds.anyone else having issues with kessils and corals?

[40gal]

I'm having similar problems, and was using China LEDs prior. I had very few blue LEDs working on the old lights, and my white power supply failed just before deciding on the kessil. I'm running 35% right now I believe and I am ramping the color throughout the day. My zoas have started to open a very little bit, and my palys are pretty much closed still. SPS are doing good - one may be bleaching slightly, but good poly extension. If it is a UV problem as suggested, does changing the color vary the amount of UV exposure?

[rblackdvm]

I would start at 5-10 % intensity until your zoas open, the slowly ramp up 5% a week until you get where you want.
Of course if you have the 360 you would have to start at 13% because they turn off any lower than that.

[40gal]

I just checked my settings, and I was at 33% max intensity and color ranging from 1 to 80 and back to 1. See apex program below. Based on these comments, I just lowered my intensity during the day from 33 to 25 to see if I see any change.

70% on both channels is way way too much to start at. Unless you have sps you shouldn't ever see more than that. Start around 15-20%

I know I mentioned monti's being very touchy and easy to bleach with kessil's but not sure if I mentioned Zoa's. Three of my original large colonies experienced significant die back(they were all well under MH/T5) and it was not fungus or other disease. None will open completely and growth is pretty much restricted to around edges and bottom of rock. They are all close to tank bottom. Other smaller pieces and growout frags, including three varieties of Agave's are expanding and doing very well w/o a hic up at the light change. Ricordia, shrooms and assorted other soft doing well. The usual high light stuff like RBTA's, SPS and the few LPS I have are also thriving. The only thing I have that did not like Kessil's or MH/T5 is a big superman (orange/blue) mushroom. Don't think it will ever be happy.

[heliguy71]

maybe kessils are not as good as people claim if only certain corals wil thrive,maybe t-5 route might be better in the long run.i know my other t-5 set-up grows everything.

[Ssteve]

I'm a big fan of kessils for what they are but imo of you want the absolute best for your mixed reef tank then T5's are king, and led's are best suited for supplementation. I'm in the process of collecting equipment for a new build and I'll have kessils on it... But not without some T5's.

Interesting.. My montipora and my zoa's grow like weeds under my Kessil 360WE's.. Infact, I just put 3 new monti frags in my tank about a month ago and they have grown nearly a half inch along all edges in that short time. From my experience, monti's love this lighting. My monti's are near the top while I have zoa's both near the top and on the bottom of my tank.

In my case, my display is 48"x96"x24" tall. I run 8 360WE's. My max intensity is 80% for four hours at a color percentage of 70%. My total photo period is 12 hours with a nice ramp up and ramp down from max intensity. I will also add that I run no other supplemental lighting. I've been running the Kessils for over a year now. Before that I had Reef Tech LED's for a few years and before that I ran a pair of 400 watt Radiums along with six 3' VHO bulbs. I absolutely love my Kessils and my tank has responded very well to them.
