Replacing MH bulbs

butts182 · 12/10/2009, 07:43 AM

When it is time to replace my MH bulb (currently have a 250w XM 15k in a hanging pendant), I am thinking of switching to a XM 10k. Do I need to raise the light or shorten the time the light is on to acclimate the corals?

Is there any way to test if they actualy need to be replaced within 1 year or iff they are still good?
