Which night light is best...?

I have a 45 gallon salt water fish container with all fish and one anemone I will soon be up grading to a 55 gallon within a couple of months the tank that i have now have the stock florescent light its kind of pinkish i dont want anything to happen to my fish or the anemone till i bring the new tank which light will they survive sour of better 50/50, actinic or 10,000k?
Sounds like you've already settled to upgrade. good move.
now, in the meantime, whether you only have one strip light, I would turn with the 50/50. You will get the wavelengths that you need for the anemone next to out the toilet bowl blue look that you get from actinic bulbs.
This depends on the depth of the tank not on the gallons of water. Light is spellbound by the water.

You need to check the requiremnts for your particular anemone but most approaching bright light with blue so actinic would be best for them but it does spend on your species
Probably the 50/50.
It doesn't business much for your fish, but your anemone, if it's one of the photosynthetic ones, needs lots of bright light.
id upgrade the light fixture a stock fluorescent isnt that virtuous coral and anemones are pretty high demand i would get t-5 lofty output bulbs. You get more lumens/wattage with them. However, any light fixture will be expensive compared to a T8 fixture
Answers:    You do realize that the 50/50 just combines the 10,000K and the actinic?

It's good to have both types, although I deem most reefkeepers prefer to keep the tubes separated into the 10,000K and the actinic and put them on two different timers. They you can turn the actinic on in the morning for about an hours back you turn on the 10,000, and at the end of the day, you turn the 10,000K off going on for an hour before the actinic. This way, you don't shock your fish with a sudden explosion of buoyant, it gets brighter gradually, and they go rotten the same way, just close to what happens when the sun rises and sets. Plus, some corals need this type of light correction to reproduce.

If your hood has two tubes, I'd go with the 10,000K and an actinic. But it sounds to me as though whether you're using stock tubes, you may just have a Normal Output hood, not a compact fluorescent or a T-5 system. An anemone won't survive long under NO fluorescents, they call for the brighter lighting of the other types. If what you have is NO, upgrade the type of light instead of replacing the tubes in the hood you enjoy. Both of the others come in 10,000K and actinic too.
Are the coralife floraglo neutral bulbs pious for planted tank?   WHAT SALT WATER FISH SHOULD I GET?   Whats wrong next to this boring fish?   Does anyone use Coralife ColorMax Bulbs for the fish cistern aquarium ?
