Planted tank.. I have a 55G and getting dual T5 48" but which bulb?

[Hooperman42]

I have a planted tank with Betta and cory's and loaches. Want a bright tank but would like the plants to thrive without CO2. What would you suggest or bulbs. I love the ATI Aquablue that I use on my sons 20L snail tank and I use it with an ATI Deep Blue. But for this one its bigger and will of course us two 54 watt T5 HO's. What would you suggest, I really dont want a pink hue to the tank however. So would things grow if I did the Aquablue special by ATI (if you dont know this light dont guess at it as it is very white with a small hint of blue - It is 12K...and just beautiful clear light. What do you think or reccomend? I am not a plant freak just want some nice plants to grow and not wilt. Advice please!!!!!!!!
