Help with bulb choice

[Nikki777]

I'm planning on getting the T5- five lamp fixture by Aquactinics. What would you recommend for bulb choice for a 80 gal tank that it 20 inches deep? I have soft corals, LPS, and one SPS. What K rating should I go with and how many white bulbs vs. blue bulbs since the fixture fits five of them. Thanks in advance for the help.
