Best color temp for FOWLR?

[schudini]

I have a 20g FOWLR tank (without fish yet) and I'm curious as to the best color temperature bulb to buy for the hood.

Right now (for the cycling), I used the bulb that came with the hood. It's 15w and kind of pinkish (similar to a grow light). The problem is it's great for growing algae (already started growing on the glass and rocks, and the tank has only had RO/DI water).

I'm looking to buy a replacement (same wattage and length), but in a different temp. My three options are...

50/50 combination of 6500K trichromatic daylight phosphor and actinic 420 phosphor

10,000K

pure 420nm actinic


I don't know which one would be best for reducing algae growth. I have no intention of adding coral/anemone to the tank.

Thanks for your opinions.

I like the 6500K and 10KK (get it?) combo.

I like 10k because it shows of fish's colors really well IMO
I feel like it brings out the color in orange/yellow/red fish... at least that was my observation.

I'll be getting new MH bulbs next month..... switching from 14k to 10k, for the reasons pointed out by fishfreak
