Is actinic lighting good for your tank?

[Driller31]

Are the blue lights better for coral, as opposed to blue and white lights? What are some of your thoughts on this?? When the white lights go out and the blue are the only ones on, all my coral and everything in my tank look way better..So I was wanting to take the 2 white bulbs out and just have straight blue light, is this a good idea??

And what are yalls thoughts on moon light??

Actinic (420nm) lighting is important for coral growth, but they use light in the full spectrum. If you are doing a grow out tank then 6500k (sunlight) would be great.

I run two super actinics and two 50/50`s. I personally like alot of actinic in my tank. Have had good results.
