New PC Bulb questions

[Dusty44]

I currently have a 96w dual bulb powercompact light fixture. One of bulbs I believe is a 6700k/10000k daylight bulb the other is Actinic 03/7100k blue and purple bulb.

My question is which of these 4 lights are necessary for my tank. I was thinking of getting an all blue bulb to add more blue to the look of the tank. I was also thinking of changing the 6700k for a dual 10000k or even an Actinic/10000k or 7100k/10000k here is a link to a list of bulbs

i would do just one 10k and one 7100k bulb

I agree with daugherty!

so i would not be removing anything beneficial my corals need by replacing my 6700k with a 10000 and replacing my actinic 03 with a 7100 blue. Just want to make sure before I go get them tonight.

Is there a benefit to my tank by doing this or is it just preference of color?

thanks

6700k is too yellow.You need more than 50/50 split to balance the color.In that regards,I agree with the rest,use 10-14k for daylights with actinics.The only benefit is maybe less algae problems since algae thrive on the lower kelvin like the 6700k.

I would go with the dual bulbs.\
10000k/actinic 03 and the 10000k/7100k blue
