Lighting question

dopey26776 · 04-10-2006, 01:21 AM

Trying to figure out what is a good amount of time for the lighting in my tank.
I am running t-5's, seem to be good lights, but am wondering if I am keeping them on for to long. By the last hour or two I have the lights on all of my corals seem to curl up, or close up. Is that a sign they are looking for darkness? The next morning they are all fine. Currently have them on for 11 hrs. Thanks for any input

Did you adjust your timers when the time changed?

If so, then your corals may still be on the same light schedule as before, but now that us humans have manipulated time, they still need to readjust.
