New PC Bulbs

The Saltwater Kid · 02/27/2007, 11:51 AM

Should I replace my old PC bulbs (130w total) with the new both at once or would that be too much of a shock for my corals? Maybe replace 1 bulb and after a couple days replace the second?

i'm guessing you have a 2x65w pc fixture?

IMO, i'd just do both at once and maybe run it for a couple hours less for about a week or so, but thats just me. I've replaced all 4 of my 96w pc's on my 40 breeder at the same time and never saw any ill affects.
