Q
What color bulbs should I combine for my reef aquarium? I like a more blue color overall but want to make sure I provide the correct amount of blue and white light. I have a 4 bulb fixture and was thinking of using the Actinic Blue, the Aqua Blue Coral, Aqua Blue Azure and then I'm not sure what else to use
Hello - the spectrum depends on the look you like. In a 4 bulb fixture, many hobbyist choose to put the 2 outer bulbs of the same spectrum and 2 different spectrums in the middle. Actinic Blue is a popular color and also provides a good growth spectrum.
Love these lights!! Ordered them last year and I love them and I just ordered two more ;). Everything looks amazing under these lights. Great colors and great growth!!
ive been using ati bulbs for some time now with little success in finding longevity and the perfect color mix. i recently purchased this brand and am very impressed not only with color, but my corals response. thanks geisamann
