Hey guys, right now I'm using 4 ATI blue plus, with 1 ATI Pro Color (going to replace with Fiji purple soon), and one ATI Aqua Blue Special. I have 3 other tanks going, with similar combinations.
The order of the bulbs should be spread out, just to avoid having the front of the tank look too blue or too white. So generally the order would be:
Blue+, Blue+, AB Special, Fiji Purple, Blue+, Blue+
You can also rearrange the wiring if you'd like all the blues on at once, because on the Sunlight Supply fixtures one ballast does 4 bulbs, the other 2.
As far as photoperiod I have the blues on for 10 hrs, and the white bulbs + blue for 5 hours.
Thanks,
Brett
