Lighting types

[billb]

I have 4 65 watt duel PC's for my lighting.
2 420nm Actinic
2 460nm Actinic
1 6700k Daylight
3 10000k Daylight
(...in other words the tank is lit by half actinics / half daylights)
This is over a 29 Gallon Tank.
My question is, would it be benificial for corals if I switch out one of the Actinics to another 10000k, or just leave them as they are. In other words is 260 watts, 260 watts no matter if it's actinic or not? or will changing the actual color give me better luck with some corals.
thanks,
Bill

i would leave it like that u want a good half and half mix of daylights and acitinics gives a more full range of real light.....

I don't get it.
You say you have 4 65w dual PC's - and describe your 8 bulbs....
Then you say you have 260 watts...
8 * 65 = 520

Sorry for the confusion..
each bulb unit is 65 watts total, I have 4 of them.
Each bulb unit is actually two bulbs in one, and can be bought with various combinations. This way, one bulb unit could have a 10000k side and a 6500k side, or both sides could be 10000k each. You can mix and match. Here is a photo of one bulb unit, and you can see the two sides. this one bulb unit would equal 65 watts total.

talk about them like this to help yourself avoid confusion
daylight
actinic
or 50/50
and to answer your question no your set up is fine and all that changing and actinic bulb to a 10000k will do is make your tank look more yellow

Ok... Thanks much for the info, looks like I'll leave em alone...

When it comes time to replace them I would do away with the 7100k actinic and go with all TRUE Actinic which are the "Actinic 03"... unless you just like the look of the blue 7100k bulb??
I have the same setup on my 55g and run 2-10,000k & 2-Actinic 03s.
