Actinic and the 10,000K Ultra Daylight is for saltwater tanks. Return them. I also had to return the 50/50's that came with my Power Compacts from Custom SeaLife. I did try them (for about 10 minutes), and was shocked at how bad it looked! The colors were 'washed out' -- it looked very strange...
I'm using 6700K's now, but between 5500K and 8800K is good. The 8800K is the limit for me - I tried those too. When the 6700K's I have start to wear out, I'd like to try 5500K's... HTH
