Thanks, maybe I will go with the PC and change them slightly earlier than the year mark in that case.
Thx guys  |
It would also depend on the light demands of your critters, and also if you are running more than one bulb. On a two lamp system, I am sure you could squeeze out a year by changing one bulb at a time. I put my bulb back in, and changed the actinic to one that was only slightly used. I also removed the glass cover to maximise the amount of light the tank receives. I will now try for a one year change out target.
