Can SPS have great coloration using only blue lighting

[bif24701]

Thanks guys for being so worried about me but I stuck with leaving the whites on.

Well this is very different. I forgot to mention lights like Kessil have what they call Kessil Logic. Kessil Logic prevents you from having to many choices and possibly setting the light so that it wouldn’t support corals well. What they due is each selection of color retains the spectrums that corals need and adds or subtracts the spectrums to suite you. So with this you always will have blue in your Kessil lighting spectrum choice. One of the best features on any LED fixture IMO. That’s a reason I have two AP700s on my tank.

For those curious here is the video Jason Fox talks about what lights he uses.

Yea so several times he mentions actinics and BLUE Reef Bright strips. So yea blue and lots of blue mostly blue..

Yeah I was reading about that on their website. I’d like someone to actually test it on the deep ocean blue setting.

But not ONLY blue, which was the OPs question. He also uses geisseman actinic blue t5s not plain actinic t5s, which again, aren't only blue.

Nothing wrong with mostly blue ; )

Going to be adding 4-bulb T5 to my system, any recommendation on bulb choice? I was going to run geisseman actinic blue but not sure what to combine this with or how many of the same bulbs to run.

System is all SPS.

There are a couple of questions that have to answered - which wavelengths are required for expression of coloration, and which simply are needed for fluorescence. At present, the answer, thankfully, is that blue wavelengths are needed. But there are caveats, in Clade D proteins, wavelengths at 450nm (more or less) will induce coloration. At 40nm, coloration transitions from green to red will cease. So, the answer is - it depends upon the type of coral. I can follow up if we have specifics.

I recently had the same question and was given opposite answers. (Reefers) I have an old school Oceanic Biocube with compact fluorescents. I recently switched to all Coralife actinic. I have a mix of soft, LPS, SPS, and photosynthetic. Is this ok, or do they need a daylight bulb as well? If they do require a daylight bulb, would I be ok using a Coralife 50/50 and one actinic? @reef lover I believe you just touched base on this.

Thanks for the reply and insight.

Its mainly SPS Acropora that I am aiming to color up and grow out. I will be adding (4) T5 bulbs right now and possibly (4) more down the road but for now I was going to possibly use the following:

- (2) Giesemann Actinic Blue T5 80W

Looking for suggestions for the other 2 bulbs...

There's a typo in my reply - color transition from green to red will cease if only light at *470nm* (not 40nm!) is used.

So in your opinion what should I used for my other 2 bulb selections?

Hopefully he answers, but I think Dana shies away from making specific recommendations. He is interested in a more academic approach and leaves it up to us to,figure it out beyond that. I am trying on my upcoming build a combo of purple plus, blue plus and actinic bulbs to,supplement a 20k acrostar mega4z pro led array.

Edit: I really appreciate your work Dana, thank you!

 

[29bonsaireef]

Add a Coral+ to the mix, or two..

Fair enough... I am sort of looking for recommendations simply because nowhere local stocks T5 bulbs in 60" lengths I need to order them in and sort of want to get it close first order around haha.

So you are going with this selection:

1) https://premiumaquatics.com/products/ati-blue-80.html
2) https://premiumaquatics.com/products/ati-80w-purple.html
3) https://premiumaquatics.com/products/ati-80w-true-actinic-03.html

Possibly:
4) https://premiumaquatics.com/products/ati-80w-coral.html

 

[rushbattle]

I think you might have to just try some combos to see what you like best with your eyes. The coral will all be fine with mostly blue light, in most any combination of Kessil Logic and ATI T5 spectra.

I looked at some of Giesemann's lamps, and they seem to have at least some red in them - something you want to avoid, correct? If you really want to experiment with light, try a couple of black lights. Although their output is mostly at 365nm (UV-A) they do produce some violet light. These wavelengths are known to promote photosynthesis, but will, of course appear to be dim, and the output, for the most part, can't be measured with a PAR meter. Reefers have tried some crazy things over the years, although I'm not aware of anyone who has actually tried this.

Thank you! I really need to get in the lab and do some work on the Emerson Enhancement Effect, and effects of infrared radiation.

Where on earth do I get 60" T5 black lights!!! haha

 

[Dana Riddle]

Never said it would be easy. Reefing was built upon ingenuity when faced with a difficult situation.

 

[greg 45]

Dana your last comment was using t 5 black light / are they the same as actinic .
Or did I read this wrong .

 

[rushbattle]

@Dana Riddle I just read where you mentioned that 420nm doesn’t contribute to fluorescence. Is that so?
