Which is bluer? ATI Blue Plus or True Actinic?

ReeferKimberly · 02/25/2014, 04:07 AM

As you can see to the left, my tank is not very blue (and that is WITHOUT the CFLs I also have over it at the top to grow/harvest the xenia up top). I have been happy with it as I get good growth and my corals still do show some nice colors. I would like to add a little blue to make some of my zoas/sps pop though and am having a little trouble figuring out which bulbs to buy.

Which is more blue, ATI Blue Plus or True Actinic? I have seen someone say actinic was more purple but then someone else say that it was the most blue :/

or this?

I have some CFLs (not turned on in the picture) purely for growing xenia and they are quite white so I want to counter-act this. I also have several different T5 bulbs on the tank right now, I threw away the boxes but they are 2 white, 1 blue, 1 purple. I will be replacing 2 of them, probably the whites.

Most blue? The BLUE plus.

Actinic bulbs are violet and dim to the human eye.

actinic are very dark, almost blacklight, looking bulbs, they make the colors glow the most.

The blue plus will be much brighter, and bluer, and will get much better par if that is your goal.

Thank you for your answers

They only had ATI Blue Plus in the wrong size so I had them compare the lights to Giesemanns and we found their 'actinic plus' to be the closest to the blue plus. Updated pic in avatar, turned out well.
