Lighting question


Active member
Usually I have my lights programmed to come on about 2 PM and ramp down to off at 10 pm. I want them to be on when I'm home and not come home to a dark tank.

Recently I wrote a new program to come on 2 hours earlier to use on the weekends when people come over and I don't want them to look at a dark tank. Is this any problem with my corals? Same length and intensity of photoperiod just at a different time of day.

Mixed reef but mostly SPS with a few chalice and cyphastrea.
