CF's to HM's lights - How to break in aquarium?

[westwind77]

Last night I switched over my CF fixture (4x65w) to a MH fixture (2x250w 10k & 2x96w CF's). How should I break in the aquarium to the new lighting? The old lighting would be on about 8-10 hours a day. I ran the new one about 3 hours last night. I do not want to shock anything so I was curious what your suggestions are?
Thanks!

thats a big upgrade. u'd definitely put eggcrate between the light and the tank to begin with. also, hv the light on only 2-3 hours to begin with, and increase by a hour by 1 once a week.

was just wondering why the eggcrate?
