light bulb change

if the frogspawn and the hammer in you sig are the only 2 corals
your in luck

change the lamps on a day you will be home all the time
watch the corals after a few hours
if they show signs of retracting - turn off the lights
if not run them the normal amount of hours you did before

LPS corals can tell you they have had enough light, by deflating thus expossing less flesh to the light

with PC lamps, its possible the upgrade to new lamps, will not make any difference to them
but always worth monitoring if possible when making the change
