    Ok so the question now is go with mh or t5? I was going to go with t5 6 t5, 3x 12000k and 3x coral blue, but now i have the option i can add 2x 70w mh with a 14000k bulb what would work the best? Im going to use the mh for other tanks im setting up so i have them, the price for the t5 and the mh is the same! What to do?

    I changed from 4 x 24w T5's on my nano to a 70w MH and I must say I was very disappointed in the light output, I wouldn't buy a 70w MH again unless it was for a very shallow tank, about 30cm's. Just my experience.

    150 w MH would be great for that depth

    it'll work...but not for sps...if you want sps i suggest you use 10000k globes in those 70W MH as they output enough Par for sps.
    then add maybe one or two pure actinic t5's to get the colour right.

    but 2x70w 14000k will not be enough for sps growth

    or keep your 14000k globes in the 70W MH and add 2xt5's 10000k to give you better PAR,then you can keep sps easily
