8- 10 hrs
How many hours a day is recommended for mh I HAVE A 60 G BOW FRONT with a variety of soft corals I have a 250w 20k mh brand new I'm just not sure how long I should leave it on everyday
8- 10 hrs
I have PC's and MH over my reef, and I keep the PC's on 12hrs and the MH's 10hrs- I also have LED moons running opposite the PC's...
Hope this helps,

If you just installed that new 250W, I would only run 4-5 hours. your corals may not like you very much. I always cut my photoperiod when I install new bulbs.Originally Posted by reefer girl
