    This all depends on what you are keeping, sps, lps or softies and if you are looking for growth, colouration or a bit of both....

    If youre just going with halides then I recommend the 14000K which is a nice balance between blue and white.

    14 000K is the best then. I like 20 000K though, gives your tank a nice blue look and the corals look amazing under 20 000K, the only downfall is the lack of growth. 14 000K is a blueish white colour...

    My choice will be 14K. Reason being, it gives you good growth aswell as excellent colour.
    10K will give you excellent growth, but then you will need to supplement with blues.
    20K will be too blue, giving you good colouration but growth will be extremely slow.

    The 10000K are perfect. Swap your 2 X 4000K t5'S for two actinics to get a bluer colour. Your current setup will give a very yellow colour and you need to balance it better

    I would also like to know. I read Anthony Calfo's book and he says the best results for growth and colour are achieved with three metal halides. 1 x 6500K MH with a 20 000K MH on either side of the 6500K. So i'm sure they can be mixed...

    mnd, the 14K bulbs will give you growth, and the 20K will give you more blue. If thats what pleases your eyes, go for it :)
