24" is reaching the maximum limit of T5's from what i have read. Make sure you are placing them as close to the water as possible. I'm going to be using the same 6 bulb tek but 36" over a 12 inch deep tank. The fixture will gain about 10-20% Par if you add a fan to cool the label end of the bulbs. A cheap clip on fan will do the trick.
Bulb combo
4 ATI Blue Plus <-- very high par bulb
1 ATI Purple Plus (cheaper than the KZ - almost identical output)
1 GE 6500K daylight
swap out one ATI Blue Plus for 1 ATI Aquablue Special if its too blue.
I think KZ and ATI bulbs are both made by the same manufacturer but i cant be for sure. Maybe someone else can ring in on this.
