    I am starting a frag tank and looking for some advice

    It will be 1250 long X 650 wide X 180 High

    I have 2 X 150W MH's that I want to use - How do you suggest I hang these?

    my thought was to hang them sideways (not length ways) as I want to maximise the light on the full tank if you know what i mean

    So it would be 35cm - MH(20cm wide) - 20cm - MH(20cm wide) - 35cm

    Is that a good spread?

    Hi lockes i would prefer to hang them higher to get a bigger light spread , by having
    them angled you would loose a bit of light penetration because of reflection from the water surface.

    :) Let em try and explain

    I don't want them angled but want to know if I should hang them lengthways or width ways.....

    A MH spreads light sideways not lengthways along the unit correct?
