Giesemann T5 bulb combination
 

I am going to buy 48" Giesemann bulbs for my 4 bulb T5 fixture ....

I want something that will bring out Purple in corals.
I have a staghorn coral that shines blue under my current bulb configuration but when all my lights are turned off and I have my living room light on this coral looks more purple.

What will be the best configuration for color and growth ?

Not sure how much this will help you. I am going to use this config when I replace my lights T5 VHO lights. It is not my config got off RC not sure form who or I'd give 'em credit.

From the front:
ATI Aquablue
UVL Super Actinic
UVL Aquasun
ATI Blue Plus
GE 6500K Daylight or Giesemann Midday
ATI Blue Plus
UVL 75/25
ATI Blue Plus
"Grab an extra Aquablue just in case. They are a crisp white light with a slight blue tint. If you think the above mix is more blue than you want just swap out a Blue Plus for the Aquablue and it should get you there."

Like I said, don't know who posted this, but I am looking for more of a blue tint myself so I am going to try this when my bulbs need replacing.If you go to T5 Q & A you may find more info. Good luck.
