Hi all,
As I've posted in an earlier thread, I'll be replacing my PC bulbs soon. Over my 55g, I've got 2x65w 10000K, 2x65w Actinic 03, 1x96w 10000K, and 1x96w Actinic 03. All are about 10-11 months old. Will it be risky to replace all of the bulbs at once, or do I need to install a few every few months. I was really wanting all of them to be the same age, but I don't want my corals to suffer because of the lighting increase (i'm sure the old bulbs have lost a little of their output).
