[[[Does anyone here keep some actinic lights on all the time?  ][I work an odd shift and have to have a light schedule that I can live with but do not want to do so at the expense of my reef.][  ][I know that in the hobby the best scenario is to use a light schedule as close to nature as possible, but I’m wondering how stressful having the blue lights on at night really is.][  ][Except during the new moon the ocean always has a bit of light.][  ][What would be the least or shortest period of total darkness a hobbyist could have to keep corals and fish healthy.]]] [[[I have a 60 gallon tank with only LPS Softies and 7 fish.  ][About 200 watts LEDs.][  ][Lights come on at 3:00PM full spectrum, and off at 11P when I leave for work.. When I come home at 06:00am I like having some light to check out everything before going to bed.][  ][Before I was just leaving actinic on all the time, but have been advised that the reef needs at least 12 hours of total darkness.][  ][This advice comes from a really good source, who has never been wrong before, so I’ll do this, but would like to hear some opinions from some of our seasoned reefers out there.][  ][If there is any way to light a tank at night without stressing the eco system I’d love to hear it.]]] [[Thanks]] 
 
I'm no expert like others on this forum, but I think the advice you were given about total darkness is good advice.  When I started my first tank, I left the actinics on all night, and one of my fish ended up coming down with ich. I don't know for sure, but afterwards I wondered whether the fish got sick because it was stressed from there always being a light on. Perhaps it couldn't sleep. Depending on how dark the room is and whether other people (with normal schedules) live with you and will be turning lights on and off, perhaps you could adjust the lighting schedule to more closely match your schedule so that they're either just coming on or just going off when you get home in the morning. Just a thought. 
 
I run a Radion XR15 on my tank. I have lights on 24/7. However, from 11 pm to 9 am, it is set at 1% with the Royal blue and UV at 50. Every thing seems to love this setting. I have had it this way for about 5 months
 
[[Thanks, guys.[  ]][Just seeing these responses.][[  ]][I set two timers, Full spectrum 8 hrs actinic 12 hours and twelve hrs of total darkness and I’m seeing more growth.][[  ]][I guess we should do what is best for the health of the tank over what gives pleasure to the hobbyist. ]]
