That's all fine and dandy, but a blue bulb peaks at 460, actinic is 420.

T5HO with only actinics as stated earlier in the thread

I don't think you have enough light spectrum with just the actinic.

I have to disagree.

Maybe I missed it, but why is it not ok to give the animals what they receive in nature? Actinic light in the 420 range also promotes the growth of Zooxanthellae algae. I have been running a tank with only blues on 15 scolymia corals. The colors that are coming out now are ridiculous and they look healthier than when I had them under a full spectrum light.

I don't care if you disagree, I'm not here to debate you on this.
I think the OP needs more than just actinic lights on his tank.

You both have a good point. Although I can agree with Tweaked more because nature biologically designed corals to be under specific lighting, and if LPS are harvested within that light spectrum, then it is only natural to grow them under that same spectrum. Also, I do have some SPS that are at the top of my reef and they are looking good also. My lfs even has an SPS tank under actinics. I dont think its a matter of 'needing' certain light spectrums, rather just 'beneficial' to have certain corals under certain spectrums. I changed up my lighting the other day. I switched back to 1-15,000K bulb and 1-20,000K bulb. However, this time I installed actinic LEDs that are going to cover the first few hours of the photoperiod and the last few hours. That way I am covering more than one spectrum. I am going to be running a test with this over the next couple months to see if my acans will stay these new colors or revert back. I am hoping to turn this into a mix tank that allows for peak potential in all of my corals. Stay tuned in for updates, and Tweaked, Im gonna be keeping up with your scoly tank to see how it turns out. It looks good man.

Interesting lighting tweaked. Makes sense to me!

A wider spectrum in the T5s. Not quite a full spectrum

I agree with you.
Saying you need White Light is an Old Myth (It is about as Relevant as saying Fish Only Grow as Big as your Tank). We all know that was proven wrong a long time ago.
The Ocean is Blue and the Deeper Down you go the Bluer it gets.
Many of the Nicest (and Rarest Corals) are found Deep so they are Harder to Get too (Hence the High Price Tags).
All the Big Names (Cherry Corals, Jason Fox, Worldwide Corals) all use Blue Lighting. Seriously they have a Fortune in Coral do you think they would Risk all that if White Light was Crucial to Keeping Coral?
Besides Corals look Ugly Under White Light!
I have 6 Tanks (3 T5HO and 3 Kessil LED) All 6 use Only Blue Lights.
I have no issues and Corals look waaaaay better and are Much Healthier Under Blue Light than when I used 50/50.

Thank you for telling us how everything should be done.

I am just trying to spread the word that you do not NEED White Light.
You can Light your Tank However you Want that doesn't matter to me.
But for those that like Blue Light I want to let them know that it is OK to use only BLue Light.
It is an old myth that needs to stop being spread.
I am not trying to offend anyone.
I am just tying to educate those that care to listen.
