I"m trying to get a feel for what percentages I need to run my t247 lights at. I don't have many coral in tank now but am adding slowly. Currently yellow polyps, kenya trees, zoas, mushrooms, green button polyps

Thanks for any advise. Just curious as to what others are running at.

not much input here other than I am going 14 days with my T247 and I am @ ch1 blues @ 45% and ch1 whites @ 30%. I am thinking I will ramp up to 65 blue and 35 white and see what happens there.
I seem to have read some folks running blue up to 90-100% and whites up to 75%

I have the s026 its the same light just manual adjustments. I run slightly under 50% white channel and slightly under 75% blue channel. The highest light required inhabitants are a Fiji yellow leather and a few bubble tip anemones. They seem to be doing good. The Fiji leather is about half way up the tank and two rose bubble tips are also about half way up and a green bubble tip on the bottom of the tank.

Swapped out a low quality mh fixture (3, 250hqi bulbs) with actinic CF bulbs to three of the OR fixtures, started both channels at 100%, only one coral reacted negatively, a bubble coral, there is a second one in the aquarium only a few inches deeper that showed no signs of stress, go figure!

I should also add I have 3 fixtures centered over each 2' section of the tank about 7" off the water line.

Distance from the water and any overlap between fixtures can make a difference.

so do I want my blues more than the whites because of looks or for health of animals

Just adjusted 45 whites 85 blue everything is popping beautifully crazy PE all over tank -
Think I might leave it here for 2 weeks then adjust whites up a bit more if I am satisfied-

Blues = 20%
Whites = 30%

I don't know how you guys/gals are turning up your blues so bright? If I turn my blues up, it looks like smurf town in my tank.

I'm running them at 60/40 bw. I have them about 12.5" off the water in a 24" deep tank.

CH1=35, CH2=30, 4 T247s over my 180. Anything more, and my corals aren't very happy. Much growth on my SPS, LPS, anemone.

Note from my earlier posts, the setting number isn't the same as power. On my lights, the mapping is:
1 ==> 17%
10 ==> 19%
30 ==> 50%
50 ==> 67%
70 ==> 83%
90 ==> 95%
100 ==> 100%

So I am running mine just over 50%, or 60 watts total for each, 55 watts for the LEDs and drivers, 5 watts for the fans. My tank is doing better with 240 watts from these than it did with 1100 watts from my MH/VHO setup.

Any Disco effect on that 180? I'm considering using three units around 2 250w MH on my upcoming 180 build.

Only under the rocks if the red or green LED shines through a small hole in the reef. It is easy to fix by adjusting the rocks. Some like the effect, I personally don't.

4 of these units is way more than enough for my tank. I sure don't miss the heat and fan noise from my MHs. I had a 400w in the center, flanked by 2 175W MH with 2x110 VHOs before.

I have the S026 that I run at 100% Blue and maybe 30-35% white.

Any update on the 180 with the T247? I have 1 fixture on a 37g holding tank and looking to put 3-4 on my 210 mixed reef. How are your corals? Any increase in growth rate? Are your settings still the same as your earlier post?

I'm running at 30 for Blue (CH1) and 25 for White (CH2). I have been increasingly the blue channel slowly and see no ill effects on coral yet.

I saw a tank that I liked at 100%/40% and I am looking to ramp to that, but I don't want to singe my SPS so I am moving up about 2% a week and watching for stress.

i have mine set 85 blue 65 white and doing good.

I run the white at 65% and blues at 95%. Whites are on for 4 hours and blues for 11hours. I also have two T5 I run for 6 hours. an hour before the white and an hour after.

I should have added I run blues for 12 hrs and whites for 10.

@ClownMan727
Why such a short white period?

That is all they need. I have tried to understand why and have a theory but don't really know why. I have an mostly SPS tank and I have just tried to emulate what other successful SPS tanks have done as far as photoperiod and light intensity. It has been working nicely so far. Here is a link to some pics of my corals.

It certainly looks like you are having success. I'm going to have to think about this. Do you think the blues are driving the growth more than the whites or just that the whites aren't needed more than 4 hours?

If you noticed I supplement the LEDs with 2 T5's for 6 hours.

Nice bump so I can update. I slowly ended up hitting 100% on both channels and putting a couple T5s in the canopy to get more light and better blending of colors.

The combination worked well for what it was. The violets started burning out and decided to go a different route and replaced the 3 fixtures. These definitely let me know what I liked and didn't like and was a good price for trying something new.

I completely missed that. That makes way more sense now.

How long before they burned out and how did you know?

I'm not exactly sure when they burnt out. At least a year maybe. I could see little black spots. No light.

I was running two of these units over a 2.5ft tank for a year, it covered every inch perfectly. I had them set at 70% and 30%.

They were my first lights over a new tank and they served their purpose well for the price. My SPS seemed to so very well under them, but my softies were getting washed out. I've gone ATI T5 now, two weeks in, much better coverage and my fish are much more active now without the shimmer.

Do you think the fish are less active under LED or the shimmer or is the t5 a reduction in total light intensity?

I used a Seneye Reef to set the height of the T5 unit so that the Par on my top shelf (SPS/clams) was about the same as the LED. T5 sits about 8" above tank, T247 were at 12". I have an Orchid Dottyback that was rarely ever seen but since the switch it is out and about again.

Just for reference I measured heights, I'm currently using 6x24W, 3B+, 2C+, 1P+. So for my setup, ATI 144W T5 @ 6" is the equivalent of 2xT247 units, 70/30% @ 12".
