if its a frag tank than i assume you are looking for growth. 4 ati blue plus will give you the most par = growth.

Okay so if I couldnt use ATI. What are your options? Any competitors produce a similar bulb?

4 kz new gens

fyi, ATI isn't much better than KZ or any of the other big names

[Mandosh]

KZ Super Blue = ATI Blue+
KZ New Gen = ATI Aquablue Special

In the end I ran a 2 14000k, an actinic and some pink. Seemed to work fine for me.
