Kessils and sps

You will not find any sps dominated tanks with kessils alone. I dare you too. Try using them exclusively for 3 to 4 months and let me know if it does not brown out your acroporas. They do fine on mixed reef with some montiporas, lps and softies but not on intense light loving acroporas. There is a reason why reefers with sps dominated (mostly acroporas) tanks still use halides and t5s. They work. Look at my tank below. There are 3 AI hydra 52 in the middle. The ends have the newest kessil a360w e series. See how dim the ends are with kessils at full blast? Now try using just the kessil without any other lighting and tell me if the acropora with be better off. I am just waiting for the remaining hydra 52s to come in and I will remove the kessils. The kessils light up frag tanks ok but not 24" high tanks.

Neptune Aquatics and Diablo Corals are both full Kessil and their systems are amazing. I saw the display at Neptunes yesterday and is full on 360e on their 300. Over 1 yr on the Kessils now. Plus there entire grow out system is Kessil. SPS are insanely beautiful. So can it be done yes. Is it being done yes. Most people don't allow the LED to acclimate and let the corals recover. I miss my LED system. I should have stayed Kessil on my 93. I might go back to the new 360e.
 
Neptune's main display is 435 gallons and it was lit with AI before switching to kessil. Look at their website. I own the new kessil a360W e series. It can barely light a 24x24 without shadows. Again the kessil works on shallower tanks.
 
i am running 3 vegas and 2 kessil 350n...the vega has more shadowing than the kessil.
But so far the coloration that my SPS had gain with the vegas had been very nice.
 
Here is a comparison. Both ends have the latest and greatest kessil a360w e series. Focus on the right side where the 3 vortech mp60s are. It is pretty dark with the kessil on full blast. You know the kessil is on because you would see the light spillage in the hood.

Now look at the same region in the right when I switched the kessil with an ai hydra 52. You can actually see the blue polyps in the montipora. It is no where near as intense as an ai.
 
I have 4 kessil a360n over my 220 tank (6ft long). I've been happy with them so far. I have had some issues with color but everything seems to be slowly coloring up. It's only been up about three months.

There's a little bit of shadowing but not to bad. I was thinking about maybe using a light mover if the colonies grow big enough.

What kelvin rating are you working with? Give us your percentages please
 
I don't know exact percentages. I have it @ 100% intensity and the color spectrum @.around 10K . I have been just using the knobs.
 
I think you will see more and more as time goes on. Takes time to grow these massive colonies and the first Gen leds that came out didn't seem that great to me. Time will tell.
 
Sorry guys haven't replied in a while to my own thread. I'm still in the market and looking. This will be a multiple month research and money saving endeavor. It is going hand in hand with a stand sump and tank upgrade, ideally keeping all of my current inhabitants, and using mostly new rock. It's a lofty goal but I know it can be done. I'm still researching and very interested in kessils. Having seen some more info it looks like the chip uses a combination of 4000-4500k neutral white, 450 nm royal blue, 480 nm blue, and 395 nm UV (which on a close up, appear as black specs since the human eye cannot detect 395 nm. These lights are to my knowledge the only LEDs on the market that offer this spectrum, even the radion pro and hydra 52 having their "UV" peak at 405 nm if I'm not mistake. This 10 nm difference seems to be a fairly big deal to coloration and growth from what I gather, and is what allows kessils to rival the response of much brighter and more powerful metal halides.

If I'm talking out of my arse please someone correct me and I'll accept it, this is just the conclusion I've come to so far. I hate to say it but I've also seen some pretty spectacular results on some major sps tanks using the reef breeders photon series which I am also considering, as it would provid even coverage, high par, and half the cost. But I've not made my mind up. I've also been researching BML as they are soon to release a new model that allegedly looks identical to a 400 watt radium. Anxious to see if it's true. Their center of operations is nearby me so I will be able to check them out first hand. They're fairly pricey though.

Happy to continue discussing, learning, and being educated and corrected. Keep the pics and opinions coming
 
Bpb I used to have a 55gal sps tank with 3 kessil a350w on it. I had no issues with shadows at all and my sps had great growth. I started my new tank when I moved and had to sell them. I now have an ati 6xt5 fixture and when I get money I'm going back to kessil. I tried supplementing my kessils with a bml strip so I could get the reds and greens and the only difference I noticed in the couple months I had it was heat. I don't have a before and after pic all I have is a random one when the tank was about 8 months old

Hey I recognize you from ARC. Those colors are great. I've also considered the a350s since I can find them used for fairly inexpensive compared to the new ones. I was considering the new BML fixtures but for what id need, I'm running into kessil money there which are atop my wish list. Even higher than radions or ghl

so when you get your kessils back will you be supplementing them with anything? or just have the kessils?
 
Here's another question. Do any of you run kessils in a canopy? That's kind of a big deal for me. My tank is opposite the television, and if you're sitting on the couch I have found lights outside a canopy cast an intolerable glare on the tv as they reflect off the screen. The tank reflection you can surprisingly ignore but not direct reflection from lights. My t5s have a light shield to prevent this. Most people seem to use the gooseneck mounts to get the kessils 12-18" off the water. I don't want a 2 foot tall canopy over the tank as that would look silly. Can these be hung from an open top faux canopy say 6-8" off the water? Or is that too close. Keep in mind i run a 55 gallon. Only 12" depth. When I upgrade it'll only be to a 75 gallon so that'll be...18" depth? Don't need to cover that wide front to back distance of a cube. Also...my aqua scale has two mountains with a valley in the middle under the cross brace. The sps are mounted on the rock mounds, while my zoas and Lps are in the middle on the sand. So two would actually be ideal since the sps would be directly under each unit, and a 3rd would be over the cross brace rendering it strongly hindered. My aqua scape actually works in my favor since the sps are at the ends and not in the middle or evenly spread.
 
Also since this is my thread I may as well post a tank pic.
