Which Combo for the best Corals???

[Strickland_673]

In have a hagen GLO 2X24W,

and I have

Giesemann:
1 X AquaBlue + = 60% Actinic 40% combination (15000K)

2 X Actinic + = peaks at 450nm (22000K)

but i only have room for 2 bulbs, should i do one of each or 2 actinic +, tank is 15" deep and i would like corals at some point. i know i wont be able to have all corals, but thats down the road.

Thanks Again
