need bulbs, have quick ?

As stated in my previous thread, I'm building a macro algae filled mantis tank. Build thread coming. I have a 2x39w T5 fixture. Since I'm not worried about lighting for the mantis itself, I am looking for a good bulb (or at least a color temp) to use to aid in macro/coral growth (coral being very easy softies...ie xenia/kenya tree).

How big is your tank?

color temperatures in the range of 6500k are a good choice for macros.

40 gallon breeder. The light will be hung above the tank, so there will be about 6" to 12" of space between the two.

you could mix some 6700k with some 10 k, macro will grow under both, but the 10 will keep it from looking too yellow
