I can not decide the number of Actinic in my new tank.

I need your help...

I decided the MH combination in my new 100gallon shallow tank.
I divided 2 section. the left side is 20K radium(250) at the front+6500K
Iwasaki(150)at the back. all is SE bulb... and the right side is 14K AC(250)
at the center....I will be use two canopies...

and I am thinking of actinic supplement and have icecap 660 ballast and
the number of maximum bulb I can install is 4...

the length of canopy is 65cm...so I should use 24inch bulb (VHO or T5)

1. Best number of actinic bulb...(2 or 3 or 4(max))
2. the best combination?(VHO only, T5 only VHO+T5)?
What is your opinion? :pat:

Thanks in advance..

3weeks ago Bob recommanded the VHO+T5 combination and I think It is OK for human's eyes and corals health & coloration both...but I do not sure 2T5+2VHO is
good...I wanna use 2~3 bulb...how about 1T5+2VHO like Edward,invincible's tank....
