So I assume you checked out the hybrid saltwater / mechanic store. Dude is very cool and has some nice tanks using kessils. He got to buy kessils as well. I was pretty blown away by the color and size of his SPS.

Been following this thread for a month or so... I set up a 95 gallon in December. It's 30 x30 x24High. I have an A360N over the tank on a gooseneck. Only running at 70% currently. I have SPS under the light on a ridge of rock and sps and chalices further away as the light spreads. Wondering if this will work?

I would have gone with the 360w, that narrow should be at least 12" from the water. It will fry stuff. I've seen 350N mounted 18" from water and still growing great corals at the bottom of a 30" tank or more. Start lower. Maybe around 50% wait a week and increase 5%.

the kessils have so much more saturation than our minds tell us they do...probably based on our known success and look of MH> but even my a150w's can fry stuff. it took me 3 corals to accept they are as bright as they are. i now start high light loving sps on the sides of the cone and move them inward. LPS are all at the bottom of the tank or the outskirts of the cone.
What is very cool is to have low light corals up high in the tank as i have gotten a pretty good feel for the lower light areas of the cone, so i have some mushrooms and lps growing right up on the top of tank just behind sps in the field of view....it doesnt look normal, but it is working this far...and i have raised my a150's higher (about 12") from the water surface, because any lower and i felt the range narrowed too much and really had too high of penetration directly under the units.

I have a Kessil a350W in my 50g tank with 40x18x18 inches. the height of the LED tube is 12 inches of water column. I wonder the experts what is the best setting to not harm the sps.

Hi Claudio... 12" its too much for the W version. About 7" its ok... unless you are looking for bigger coverage area.
Start at 50%, check your corals and then increase a little bit every week.
This is my friend´s tank with 2 Kessils A350W over the tank, so you can have a reference of how far his Kessils are placed.

On Bif's suggestion I swapped my 360N for a 360W. I thought it was torching everything. Can someone growing SPS with an A360W post their apex programs? My tank is a 100 gal cube 31 x 31 x 24 high. light is on a gooseneck 7-10" off water. Thanks.

Being that you have the wide now and need 31" spread I would mount them around 6" off the water and then see what your coverage is. 10" seems pretty high.

You do realize you just replied to a post that's from 11 months ago and a thread that's had no discussion for over 8 months.
Slow day at the office ? :eek2:

Better late than never . LOL .Based on this thread I can see your a kessil fan reefvet . I would love to see the GA corals you have with a growth sequence . I am unsure if those corals are in the tank with the sunlight assistance.
I for one have been following this thread . I have to make my mind up soon. I think that picture with the 2 kessils may be covering 18 inches span left to right if it is a 48inch l to r tank .
It is the shadowing that I have seen that bother's me . I am a stickhead and will be doing a small tank this time 24 x 24 x 20 H. I noticed most of the led only sps dominant tanks that were successful ai,radion,kessil etc definitley had multiples of units in use . Call it overkill but they were not lacking growth,color and that observation told me a lot . I'll still keep reading threads and get to a decision one day . I do think that if I have to use t5's to assist then it's gonna be a no go with kessil or ai which are my two main choices so far . I would just stick to t5 or just use a 240/400 halide and be done with it . On the halide note a friend told me the phoenix bulb will no longer be in production . That not a good thing to hear since I have a CV DE mini pendant on hand .

I decided to go with metal halides. While I love the way kessils look...operating cost, temperature, and bulb replacement cost are not a problem so rather than deal with the learning curve and lengthy acclimation of led use, I decided to go with what will grow sps like steroids in a set and forget fool proof manner.
In the future if I get a cube tank, shallow tank, or change to all rock hugging non branching sps or all zoa and Lps type coral stock, kessils will be the choice without a doubt. For now I'm loving the big coverage and lack of shadowing the large MH reflectors provide.

I currently run my A360we at 90% over a shallow tanks and have gotten great results as far as coloration and PE goes. As far as growth it is ok, but not to be compared with MH,AI or radion. I believe thats something you should ask yourself to, are you looking for explosive growth? Some don't want to have to snip their corals every few months so its all a matter of preference IMO.
