The light fixture I ordered (2x18w t5HO)claimed it came with a 10000k and 460nm bulb.. so I ordered two 18watt 6700k bulbs as I realized 460nm is not really used in planted tanks...

Well I get the fixture today and come to find out, its not a 10000K bulbs, its a 12000k bulb.. I realize a lot of people use the 10000k for planted tanks but could the 12000k be used? seems as though it would be too much in the blue spectrum... should I just get another 6700k and run both 6700k?

I went with the 12000k and 6700k, it's a good mix, but the 6700k is wayyy more red then 6500k! lol, didn't know there would be that much of a difference.. and the 12000k is just a hint of blue, definitely a good color mixture, easy on the eyes and great for the plants.
