Product Questions

I have a 12 lamp fixture. I was thinking about using 6 aqua blue and 6 blue plus. Is actinic blue better than blue plus? Should I replace two of the blue plus for coral plus or purple?
Question by: Jon on Jan 28, 2016 1:38:00 PM
Great question!
If you are looking for a slightly deeper blue color having the additional actinic can work out well! For us we typically recommend even between the aquablue special and blue plus with a few supplementary bulbs of your color choice to help spread out the spectrum. Feel free to let us know if you have any further questions!

  • Best T5s ever. By squareface on 12/18/2015

    Great color.
  • A must have IMO. By Mitch on 12/16/2015

    This bulb makes colors pop some. But most of it's spectra is a wavelength of light we just cannot see. I wouldn't say that my corals colors became brighter under this light. But richer. After a month you will see the difference, if you have not used a bulb of this caliber before.
  • LOVE IT By Russell on 12/13/2015

    BRS is the best my Corals love this light and so do i, i use this light to wake up my corals and to put them to sleep they are a great light and works better than most
  • no difference By a grandis on 11/30/2015

    Well, I've used this bulb in a 8 bulb Power Module ATI fixture and I couldn't see anything positive from it. I actually notice that is was weak to the eyes, consequently affecting the overall aspect of the tank. I changed for an ATI blue Plus and that was a better choice for the PAR alone. My combination at that time was 2 aqua blue special, 1 true actinic and 5 Blue Plus bulbs. Never used it again after that.

    I believe the health/colors of the inverts need to come from other sources than pure reflection from colored bulbs. The protein pigments are reflecting from light source, but in a natural way, more towards the 10000K - 14000K range of the spectrum.
    I also believe that nutrition from particle foods would help colors found in most cnidarians.

    Aloha,
    Grandis.
