Atinic Lighting
Ok,
Can someone please settle this for me.. I have had some confusing conversations on this one.. Is atinic lighting simply for looks or is it important to the health of the corals? Thanks Chad |

It's not necessarily the actinic lighting itself that's important. It's the specific spectrum of "blue" light which corals need.
So if you use let's say a halide "iwasaki" bulb over your 50g cube tank as your only source of light. You corals would do fine. That bulb provides a full spectrum of light which contains enough "blue" spectrum for corals. If you added some actinic supplementation to your Iwasaki bulb it would make the overall appearance of the tank seem more white and at the same time increase the "Blue" spectrum of light. It's not necessary but it may help with coral color and Coraline growth etc.etc. So no it's not " always " necessary but it depends on the situation. cheers |
Blue color is what is left when the other frequencies are filtered out as one goes deeper into the ocean. Thus logic tells us that if we supply full freqency lighting to our corals they will grow and be "happy" Remember please that corals can't "see" worth a hoot. :onfire:

Remember please that corals can't "see" worth a hoot because they have no eyes :onfire:
Ater saying that, guess who has actinic lights on both of his tanks. :BIG: |

The reason I ask is that my DIY hood may not mount the lighting I had planned.. Would you say two 10K PC lights would provide enough blue spectrum? Ove my 20g nano btw..

A larger spectrum of blue...aka actinic IS desired by some anemones (refer to Joyce Wilkerson). It is also the most esthetic part of lighting the reef for me, aside from moonlight.

Well, I planned on having two 20w atinic's along with my 2x 55w 10k PC... but turns out the 20w are a bit too long for the hood.. I really like the look of the atinic tho.. I am using a 15w one ATM... but I thought the two 20's would look better with 2 10ks...
