Why all the AI's for sale?
Seems like everyone is selling theirs, something new for around the same price I missed that's come out?
Was thinking about a set rather than replacing my MH bulbs when they're due but seeing so many FS lately has me wondering if I should stay away.

They might all be upgrading to the new full spectrum AI Vega.

Yes.
Also a lot upgraded to radions when the price cam down or the new ghl mitras I myself sold mine as I'm taking a leave of absence so to speak from salt water.

Are you having good luck with the Sol as a frag tank light? White or Blue? I am considering using one.

I use one over my frag section and I think it's a great light, with good growth and seems bullet proof.
That being said I'm not sure I would love it over my display as its missing the full spectrum.

Perhaps not full spectrum, but I prefer a bluer look. Still not convinced that all the schmancy colors of other lights does anything different. If I were re-purchasing lights, I would buy them again. Great value for the cost, comparable to Radions in my opinion, and great control using my Apex. edit: I use the Blue model

Yep if you look at the ocean, where there is red light there is algae. Once you penetrate the ocean deep enough the "red" light is the first that gets filtered out. Hence after a certain depth...no algae's like there is towards the surface. In a tank it means nothing, our tanks are not deep enough to do this... I sorta think the spectrum claims of LED manufacturers admit of a bit of snake oil i'm afraid, rather their claims of perceived benefit...but again LED is relatively new...so time will tell.

Something I've read on other forums say that the full spectrum is not mainly used to improve growth. You can have a perfectly healthy and growing coral under just Blue and White LEDs. However, they pointed out that there are some other photosynthetic pigments in coral that will will peak at other light wavelengths. By giving those pigments the wavelength they peak at, they will supposedly show better color overall.
Not my opinion, just something I've read. I'm still trying to decide whether or not the Full spectrum is worth it for my next upgrade. Personally tho, I've had a few coral change color on me with my current T5s, some of them came from Blue/White LEDs, some of them came from T5s. So I'm not sure what to believe. |

I am going to try a couple of LED pendants as sort of a spot lightning or highlighting effect....when i build the system as the pendants were free - so maybe I will convert. But the 'perceived" downsides to MH were never a problem for me. I have seen as many people in support of LEDS as there are people who went back to MH,t5 from LEDS - Choice is good and there is an abundance of choice in lighting. Many zooxanthellate corals have their bright colors because of a family of multi-hued fluorescing proteins. These pigments seem to be produced in response to a given light environment. The primary control on their production appears to be total irradiance level, and little evidence exists to suggest that the "k" rating of bulbs will influence their production. There is also a strong genetic component, although the specific aspects of fluorescing proteins and their respective genes have not yet been worked out. The color temperature of light bulbs most likely influences the perceived color of corals in a tank, with ultraviolet components enhancing highly fluorescent pigments. Certain bulb temperatures may have enough of their spectrum skewed in relative distribution that total irradiance with a given wattage may be affected, and thus total irradiance influencing the relative production of fluorescing proteins.
