Well i am in the process of replacing the bulbs on my coralife PC fixture. It is a 260W fixture with 4 65w bulbs. It came with 2 10000k and 2 Actinic 03 bulbs. I am planning on replacing with 2 10000k bulbs like it came with, but when it comes to the actinic i am torn. Should i put the actinic 03 bulbs back in or one of these others that i am considering. The problem i have with the actinic 03 is that they r very purple and the tank looks a little funny and dull when just the actinics are on. On the website that i am buying the lights from they have all the bulbs the 10000k are represented as white, the actinic 03 as purple and the 7100K as blue. They make a actinic 03/7100k bulb or just a 7100k bulb. Would using one of these two either the 50/50 or just the 7100k be beneficial or detrimental to the tank. Is one better than the other or should i just get the actinic 03 again. Oh yea and there is a 1000k/actinic 03 50/50 also or is that to much 10000k and not enough actinic light along with the other 10000k bulbs.

The choice really comes down to personal taste. The actinic bulbs are going to provide less light to the corals, most likely, but the difference is fairly minimal. If you can view some setups in person, that's the best way to go. Otherwise, I'd suggest the 10,000 K/actinic combo, since you don't seem to like just the actinics.
