Light acclimation

[saltygeek]

Short story long:spin1: I replaced an XM20k bulb with a 14k phoenix. I used the screen method but I guess I underestimated the par difference between these bulbs. Well some coral were fine and some got ticked off. Color is all back to normal now after replacing the screen for a few weeks. I then have slowly removed it a little each day for the past couple of weeks. Now the problem....Because of my work schedule I can only have the screen removed for about 3 hrs before work. I need to find how to finish off the acclimation. I dont really want to mess with the timer and photoperiod too much as they have just recovered form what I already did, but I may have to. Any ideas? Do you think I could just leave the screen on in the morning and have no screen for the remaining 6hrs of the photoperiod. Or am I going to bleach them again. I could cut the photoperiod down but, again, Im not sure I should do this. Any thoughts/advice would be appreciated.

Why not try another layer of screen or two. You could run a few days with 2 or 3 layers remove one, and so on.

Yep. I have always started off with 3 layers, and removed a layer every 5-7 days, and never had any issues.

I think you overcomplicated it. Leave the screens on the whole day, all week. Then remove one screen per week. No worries about lighting schedules or work.

yes, I did overcomplicate it. I should have used more layers of screen but thats all I had and it always worked in the past so I just went for it. The coral have colored back up under one sheet of screen so they are used to that. So really I could figure im on the last screen and just remove it, I guess.
Im like the overly protective parent:hammer:
