Acitnics ARE blue.
Your corals will need a full spectrum of light, whites, and blues so the last two bulbs can be up to you based on what look you like for your tank. With the combo I have I have seen really good growth over the last year, from softies to sps
like monitporas and I had a killer poccilipora that like tripled in growth. It's also all about placement in the tank as well as flow. You could have the best lighting in the world and still not have your corals do well if either the flow or light intensity is off.
I would for sure have some whites in the array, no doubt about that.
