Quick Question about Replacing Bulbs

I just purchased 6 new T5 bulbs to replace the original bulbs in my fixture. Do I need to shorten the amount of time the lights are on to allow the corals to adjust? I have a sunset montipora that seems to be extremely sensitive to lighting changes and I don't want to bleach it again.

 

T5s are pretty good for 9 months, no more than a year in my opinion and that's pushing it. I run my daylights 6-8 hours and my blues 12 hours. Cut it shorter if you want to if you want to extend the life of the bulbs.

 

Only replace one bulb at a time.I usually then wait two weeks then replace another and so on until you have replaced them all.You shouldn't have to shorten your light cycle with this method. Good luck!

 

Two ways replace all of them the reduce your light period in half and an hour per week or replace one bulb every 3 to 7 days. Or you can be ultra careful like Vinny and change every two weeks. Top of the line bulbs should last a year.

 

Thanks for the help.
