What T5 Lighting???

[Sammy]

I know this is an old topic, however:

I have the aqua medic SUN, 6x 39w, I have a mixed reef, acro growing wild, other LPS and softies all doing great.

My bulbs are about a year old and need replacing and I'm gonna go for Geisamann

Please recommend combinations, I want the blues and fluorescents to pop.

Thanks guys
