what lighting spectrum?

[marlboro man]

I am just wondering which lighting spectrum is the important to a reef tank?

10,000K or
6,700 K or
Atinic?

I have a 130W PC light over my 25G tank and currently use 1 tube of 10,000K and 1 tube of Atinic.

if I want to maximize the lighting, can i replace the actinic with a 10,000K PC bulb? or is the actinic equally important to reef as well?

I was thinking about using 2 x10,000K bulb for my PC light, then added a
basic 20W atinic flourescent strip light. Would this be better than my current light setup and would the atinic suffice?

Thank for your help!
