I believe you meant actinic. Actinic lights are blue and i dont believe they are NEEDED but they take away the white/yellow color of the other lights. They also make certain colors glow very brightly, like my green mushrooms.

There is some beneficial spectrum of actinic lighting. It is generally present in other lighting spectrums (bulbs and types), but often time people prefer a 14-20k bulb and chose not to run them or they chose a lower K rating and deal with the washout of many colors due to the yellow peaks. Personally I like them and I like using them to complete a sunrise to sunset situation.

Wether its actinic or daylight, it should still be the same wattage. You may just not get the same PAR with actinics. As hop said, having to much daylight/white light can wash out your corals color. But in retrospect, your corals may grow quicker with the daylight bulbs. I personally like the look of a mixture of actinic and daylight bulbs...

the wattage is important but it will be the same no matter what kelvin you are using
wattage refers to the amount of electricity your using
kelvin refers to the type or spectrum the bulb is putting out

what kind of fixture do you have and what are you trying to keep?

sorry i forgot to ask what size your tank is?
is it a t5 HO?

but i think in general most corals and anemones will need more light than a 2 bulb t5HO if i was you and i was going to try it i would probably run a 10000k and a 6700k ...but it will look kind of yellow

thats just my opinion hopefully someone will jump in and correct me if im wrong

I would agree that a 2 bulb setup is going to be too little light for a nem in a 55. I think a 4 bulb setup w/ a good parabolic reflector would be probably be sufficient for a nem, not great but sufficient. A 6 bulb would be better if it would fit over a 55.

For a 55, one of the 4 bulb units would be a perfect match and fit very well;)

It should be 18" deep and yup, a 4 bulb is about as much as your going to be able to squeeze over it unless you make a custom hood.
