The usual lighting for reefs is 10,000K white with blue actinic. 6500K is great for plants (or algae) and zooxanthellae, however due to the lack of of UV in it the corals on the corals will be very bland (although the corals will grow well).

you can buy a nanotuners kit for the biocube for leds( they arent cheap though), and unless you bought it used it shouldve come with a 24w coralife 10000k bulb and an actinic 24w coralife

hi dear friends.....thanks for replay.

so after all ...the 6500 kelvin light is good ???

and you mean i dont want actinic light ?

I don't think that is what anyone said. If you use only 6500K lighting your corals will grow well but will be brown. The nice colors are pigment to block UV light (we tan brown, corals tan fluorescent colors). By using actinic or higher kelvin color lighting you will provide the light that will make the corals increase their coloration.

This is why reef keepers use 10,000K lighting or higher, usually supplemented with actinic.

In addition 6500K will ook very yellow on a reef tank.
