Changing VHO Bulbs

[phillips]

I'm planning on changing over to one of the PFO MH/VHO fixtures, so could someone tell me how often one should replace VHO actinic bulbs?

Thanks,

I change them over every 8 months. I used to change them every year, but they drop off significantly after 8 months from my experience. As a friendly reminder, be very careful after you change your actinics so as not to bleach your corals. It might not seem like a lot of light, but I've bleached some corals when changing out old actinics.

how do you time the lights when you first change them?
do you keep the same timers they were/will be on immediatly?

i am at about 10 months and ready to change them....

I have 3 VHO lights over my system, I replace 1 every 4 months.


I guess what I am say is that each bulb lasts me a year, but my coral never suffer from new bulb syndrome.
