There is some shading but not even close to what happens with leds.

Disagree. Being a diver for decades, I have seen shading of corals in nature and the undersides of most corals are naturally thinner with polyp density than the top, even those in direct sunlight. Its the same in my tank and its the same in nature. My reef has been running for over 3 years with only kessils. Shading is not a problem for me. If it were, I would have kept the t5's I ran for several months. I found them totally unnecessary, and I didnt like the flat appearance.

"First the sun move. It lights on side in the morning, then noon the top and then evening the other side " I can move the perceived point of light across my tank from left to right as well with my controller. The light is scattered the same way it is nature, via surface agitation. You will also experience natural scattering from reflections from the 4 glass panels and off the rockwork, etc. Like I said above, if shading were a problem for me (it isnt) I would have kept the t5's running.


"Plus the light from the sun is allot farther away and not as point source as led." That makes no difference in my opinion. If I move my lights up, I dont get less shading, I only get less intense light over all and less entering the tank.

"The waves and the surface of the ocean refract, scatter and bend light." I recreate that same refraction and scattering/concentration via surface agitation. Not sure what you mean by "bend". The surface agitation is what produces the shimmer. Take that agitation away, the light does not shimmer (or scatter/concentrate) the same way at all.

Here's a link to pictures of my mixed reef. As you can see, shading is not a problem at all for me:

You aren't having issues because you are keeping soft corals. The analogy of a single kessil to the sun is not accurate for a number of reasons. There is 100% a shading issue with larger SPS colonies and kessils.

Looking at the most recent full tank shot in that thread, I literally can't see any SPS. That's not to say you don't have some in there, but they must be small.

If you have SPS colonies big enough to be seen from across the room, you will have shading problems.

Oh for God's sake..photo evidence isnt good enough for you? You missed the blue stylo sps in the middle of the tank? It can easily be seen across the room, when it started out as a couple of 1" stick frags. Shading is not a problem for me or I would have left the t5's on my reef. Many of my sps frags are small and cannot be seen from across the room, they were tiny when I got them, but you see the growth evidence of them in the other thread.

one of 3 sps frags when I first got them

Sps heavy tank. 4' tank run solely on 1 AP700. Everything grown from frags.

Lol I mean do I have shading? Yes, of course. You're going to have some degree of shading regardless. Obviously t5s offer more spread due to the physics on the light source.
Do I have a "œshading issue"? Well I don't know. I guess that depends on your definition of what is an issue.

I think its also important to note that for an sps dominant tank of this size, they say I should have 2 AP700s which obviously would reduce any shading there currently is.

They are somewhat easy, I certainly found them so ..grow very well and are quite healthy. Grown under 2 kessil a360's only. I think there may be a myth about shading being a huge problem with Kessils, hasnt been my experience at all.
 
Glad things are working for you two and you are happy with your results. Like you, I am sharing MY experiences. I have 3x A360 over a 180g reef. I know this is half the number of units recommended but the light budget wasn't $2400 so 3 is what I get. I observed heavy direct shading from individual branches of large SPS overlapping. I am talking about SPS colonies too large to fit in a 5g bucket, not "œcolonies" with just a few branches that are a few inches long. I have 4x T5 "œsupplements" and I have also installed the kessils onto a light mover to reduce shading. I am certainly growing out corals just fine, but I have taken multiple steps to reduce the stagnant shadows cast from upper branches onto lower branches which leads to color and eventually tissue loss. The reason I have "œsupplement" in quotes is that I notice that my daily light cycle pH shift coincides with the T5 schedule, not the kessil cycle, so I believe most of my photosynthesis is occurring thanks to the T5s.

Well, ComforablyNumb, I hope you are happy. I lost control of my bladder when I saw your tank. What a mess, pee everywhere. Your fault! Of course, at my age, this happens pretty regularly, but I'm going to blame you anyway. Anyway, I'm bidding on a a Kessil 360 WE for my 90, and I will get another ASAP for my 90. Thanks for the photos and for reinforcing my decision to go with Kessil.

Here's my 7ft tank lit by 6 360WEs about 12" above the water. No problem with SPS, LPS or softies.

Did you crank up the color for the pics or do you run high color? I'm always curious what people are running since everything is so blue-heavy these days. I used to think 10K bulbs were too blue when they came out, but blue has grown on me over the years, especially Kessil blue.

My color maxes out at 48%. I used a lens filter that removes the blue and gets it closer to true color.
