i have the same fixture except in the two bulb. for one id put your actinics up front. but i run a 420/460 actinic mix in the front bulb, and a 10000 k in the back. check out my profile its got a pic of the tank and the color it puts out. let me know wha tyou think

and what do you have in your tank? if i was you id save up some money for either t5ho's or a halide fixture. I dont care for my pc's too much heat for the amount of light they put out, and the bulbs are rather expensive

thanks, go to this website and it shows you the different kind of bulbs you can get.

I have one of the 10,000k and one of the 420/460 mix. its basically like a purple and blue mix i think it looks pretty good. I just had to get that mix bulb not too long ago because my just 420 actinic went bad.

but if you have a four bulb fixture, i would do either:

BACK

420/460 actinic
10,000k
10,000k
420/460 actinic

FRONT

OR

BACK

10,000k
10,000k
420 actinic
460 actinic

FRONT
