bingo. It sounds to me like you did too much too soon with this upgrade. Just keep doing what your doing. I'd turn the MH's back on, get your photo routine established to not screw that up, and wait it out. Also, I don't really understand your lighting setup. So you have 2 MH's with 2 daylight supplements instead of actinics? Seems strange unless your tank was REALLY blue, but maybe i'm just crazy. Lastly, don't panic and try to change things too fast. Go slow, let it grow, etc.
