switching fuge light times?

[sompa]

can I change my fuge light times opposite of the tank time now even though I have been using same time for a while now? Will this cause any problems?

thanks for your help in advance

I didn't have any problems... I was on a 24 hour schedule, then I went to opposite. When I moved I had a couple of timers go bad and the fuge lights were all over the place as far as time goes... No problems there either!

I wouldn't anticipate any problems with that; if you run them during the day now just leave them on all night today (for example) and then shut them off in the morning when the tank lights come on.

Are you trying to get your ph swing under control? If so depending on your display and fuge sizes I have a few suggestions.
