light aclimation

[Big_Pun]

so I finally got a new bulb for my tank, running exact same bulb as before. my question is would it be better to raise the light up higher or run it for a shorter amount of time. it's a 250w de light

I would raise the light. If you run for a shorter period the light will still be more intense with the new bulb. Yes it would be a shorter time but it would be long enough to stress the corals.

I use a screen that I made out of a fish net. I place the handle in my overflows and the net (which I ziptied) is bent over the surface of the water. I use it for about a week while the corals acclimate to the new bulbs.

Meh same bulb should be ok

The only time I ever adjusted anything (height/photo period) on a bulb changeout was when I went from 175W to 250W. Never had any problems when swapping out an old 250 watt for a new 250.

I don't change the high or shade my light when I change bulb. Never have any problem.

Ditto. Just watch them for any stress, but you probably won't see any.
