Default What color temp do you prefer in your tanks?

Im sure a lot of people use mixed bulbs with mixed kelvin ratings but if you had grow out tanks with single bulb floresents on them what bulb color temp would you choose based on the fact that you only have one bulb.

6700k ?

10,000K ?

Lowes cool white?

Lowes warm white?

Im just setting up some grow out tanks and they will have single strip florecents on them but I still want the fish to look as good as possible.

Any suggestions?

John

If I could only use one bulb it would probably be 12k

There will be some 24'' and some 48'' fixtures.

Larger tanks will be getting a mix and much more powerful lighting. That I have experience with. Its just when it comes to using a single bulb I was thinking others would have some suggestions.

There will eventually be a mixed bag of trophs including some T.duboisi. But mostly rainbowish moorii's and Illangi's for now.

Thanks for getting me up to speed at a much faster rate than just reading alone. This site rocks!

Well I guess first off I cant stand yellowish light or a yellowish cast on the water,

But the fish Ill be keeping will be Illangi's and Kalambo's(moop like). Both have yellow coloration. Also so do the Duboisi...but they have blue faces and the kalmbos have blue in the dorsal. So I want to bring out both blues and yellows while not casting a yellow hue on the water. Id like a crisp white light/sparkling clear water. Not blue, not yellow.

After some additional reading I think Im leaning towards 10k's as a safe bet. Am I thinking right here? If so, what brand of t8's?

Thanks

Go with the "Aqua" bulbs which are normally a nice white cast that will bring out most colors. but they are on Fry tanks. You're going to see much anyhow. GE make some decent ones that you can find at LFS and some department stores.

ATI makes decent bulbs for 10k. Cuurent Makes Decent Bulbs too!

Stear celar of coralife bulbs.

ATI bulbs are some of the best IMO. Don't think they make a 10k bulb though.

YOU are right I was mistaken. my 110k were coralife and that's why Idon't like them. They end up with a veryt green tint after a very short time. COmparitively speaking.

The ones that I like are Current USA 12k bulbs. VERY NICE!

Also Hagen "power-glo 18k's"

Here are the Current USA T5 bulbs.

Another thing to consider is the Color Rendering Index (CRI) of the bulb you will be using. Just because two bulbs are 3000k for example doesn't mean that they will display colors in the same way. Here are some examples from photography.





Higher CRI ratings will display color better than lower CRI ratings.
