whats the best tank lighting to use 14k 20k 30k

It seems pretty widely stated that anything above 10K makes no real difference to life in the tank.
So it is purely a matter of what you think looks best.
I personally think above 12K looks too blue and unnatural, but others love that look.
You will end up buying a lot of bulbs through the life of your tank. So just buy a few different colors up front, and experiment.
If nothing else, you have a few emergency spares.
thanks i am getting some 14k
how high do you set your lights from surface of water
any one can tell me how high you put the halide from the water as i was told 22ins ?
don't know if it needs to be THAT high, usually 10-15 inches I would think. Mine are 10"
ok thanks
If it makes any difference, I recently replaced my 250w 14k MH and 2x 54w T5s for 3x:
http://www.tmc-ltd.co.uk/aquarium/aquabeam-1000.asp 30w LEDs. Extremely happy with them, not cheap but last 10+ years without needing to replace bulbs and works out 1/3 of the power consumption/running costs and far lower heat output, which in turns means less cooling needed for the thank in summer, which means less evaporation / power usage / running costs and more stable temperature
The LEDs give slightly lower brightness (they recommend 4 of the above for my 6x2x2 tank, but I have 3 for the moment) than the T5s and MH combined, but not by much, and the colour + shimmer is at least as good as MH lights.
Tom.
my halides are only about 6" from the water with no heat issues,,i like them close because i hate flooding the room with light
Kelvin temperature is kinda a selling point instead of true color temp.
Ushio bulbs have same output at 10K and 14K while many others will diminish rapidly as kelvin increases. I would recommend Hamilton 14K or Ushio 14K (brighter or yellower). But honestly it is not that critical with a good quality bulb.
I have perceived better results with 14K than with 10K with high efficient reflectors
