Since Reef Geek is backordered on the GE 6500K, what bulb do I want to substitute for it for growth/SPS? The other bulbs are 4 ATi Blue+ and 1 ATI Purple+. Thanks!
Aqua sun dual 54watt on 55 gallon
2 10000k
ok for mushrooms leathers zoathinds and a well feed duncan coral?
What order should I move the Aqua blue ? Can you tell me the order tank.
So like this.........?
Front
Blue +
GE 6500k
Blue +
Blue +
Hows that?
Awesome! Thanks a lot for the advice! I will change my bulbs once I get home and start the rotation schedule. So the Mid-day will give me a little more blue than the 6500k? if I wanted to change it around?
Need a suggestion/recommendation.....
I have a 90G Oceanic Tech tank and I'm running a 4 x 54W T5 retro on an IceCap 660. SPS dominated and while I've seen decent growth and color, I've been reading lately that the IceCap is too strong for the bulbs and kills them faster.
So, I'm deciding on an ATI fixture, but the Tech tanks have a 3" border all around the top rim of the tank, so the area for light to penetrate is really only 42" by 11".
Due to this, should I get the 6x39 ATI or a 4x54 ATI? Would a 4 bulb ATI fixture be enough on my tank? It seems fine now with the Icecap ballast and I've seen bleaching when moving corals from a MH tank to my T5 one.
The GE is a 6,500K bulb
The G Mid Day is closer to a 10,000K bulb
The Aqua Blues are 14,000K roughly
The higher the K temp is above 7,200K the Bluer the effect will be.
The Lower the K temp is below 7,200K the reder the effect is.
The yellowish look of the 6,500K is a combination of red and green light. Simulat to red and green on a color monitor creating yellow. However with enough Blue Light added to the mix the yellow in the 6,500K bulb is unnoticed.
Where do Purple + fall under? How many K is it?
The purple plus simular to the blue plus and many other bubs cannot be rated by the K scale. The Purple plus basicly produces a lot of blue light and a nominal amount of red light. Since the eye seels red and blue with no green it regesters it in our brain as purple.
The K scale in dirived by a three dimensional graph with red, green and white each having there specific axis. Then a piece of black iron is heated and as the temperature increases it changes color. When it is 2,800 degrees Kelvin the light it emits is evaluated on this three dimensional scale. Then it is heated to a higher temp and ploted again. When you get over 7,200 degrees the change in the pot becomes less and less at things get hotter. There is very little difference after 20,000K.
No light bulbs fall perfectly on this charting but are generaly called by the closest point on the chart they come to. Here is compressed rendering of the color chart as it relates to Kelvin temperature.
I have an ati dimmable sunpower 8 - 54w t5 fixture over my mixed reef tank......I was encouraged by my Lfs to go with 4 ati blue plus and 4 ati blue special.....I am not overly happy with this combo.....I find it is maybe too bright white....I think it is affecting my corals too....I am looking to change out all bulbs in march and want to go with a diff combination.....was thinking of trying an actinic, more blue plus, or maybe a 6500.....I am looking for suggestions.....also I want input on the new ati coral plus, is it similar to the blue special? I have mostly sps in my 75g.

Thank you for your advice! I am going to replace two blue specials with blue plus bulbs next weekend......my Lfs stocks ati all the time. How would you recommend I arrange the bulbs in the fixture?. And I can turn on bulbs 3 and 6 separate from the other six so how should I switch them?
Hello guys, just found out about this sub-forum. I really need help with this, I have 17 bulbs and only need 6 for my Red Sea Max 250 (39w). I was willing to buy new ATI bulbs but found a local reefer who was selling 11 bulbs so just bought some from him to see different spectrum's, I am still open to buying new bulbs like the ATI blue+.
My tank has mostly softies and LPS, one carpet anemone as well. I am trying to achieve a 20k type of look or something similiar ( I do realize that the bulb combination cant achieve that without further supplements).
Right now I am running 3 rsm actinic with 3 ATI aquablue special. Please advise and thanks in advance:
Red Sea Max 10k x 3 - 3 months used
Red Sea Max Actinic x 3 - 3 months used
Wave Point Tropical Wave x 4 - new
ATI Aquablue special x 3 - less than 6 months
ATI pro color x 1 - less than 6 months
UV super actinic x 2 - less than 6 months
@troptrea
Ok so if I put the two aqua blue plus bulbs on one dimmer slot then those are spots 3 and 6
I will put the remaining two aqua blue specials in the center....spots 4 and 5? Then leave all other remaining spots with aqua blue plus?
I.e.
Front
Aqua blue plus
Aqua blue plus
Aqua blue plus
Aqua blue special
Aqua blue special
Aqua blue plus
Aqua blue plus
Aqua blue plus
Then like you said I can later replace the spot 2 bulb with a purple? When do I replace my aqua blue specials in spots 4 and 5? Sorry for so many questions.....thank you for your help.
