How long to run MH?

I just put on my MH fixture over the 29g and i am going to acclimate with low hours and increase until my desired time..I normally ran my PC fixture from about 10am-6pm..And then actinics came on for about 45 and then it shut off.

I come home from school at 3pm and if i turned on the lights and left them on until 9:30pm or so and then did actincs for 30 mins and then moonlights come on, would that be okay?

 

I would cut your photo period in half from what it used to be and increase that time once a week until you get back to your desired time.

 

Usually with a MH, 6 hours or so is sufficient if you have actinics, it doesn't necessarily hurt to have more, but could depending on your corals. If your corals seem to be deflating at a certain time, that is usually a sign they've had enough light. Then you may want to cut back, or you are just wasting electricity and possibly stressing the corals. I'd have to check, but IIRC, I think I have mine set for about 7hrs right now. My supplemental lights are on for about 12hrs though.

 

My actinics are on short of 12 I think - the halide is down to 8 hours. I did have the halide on for 10 when I did not have actinics.

 

Alright ill run it for 7 hours or so a day..thanks for the help

 

You are slowly bringing it up to 7 hours right? I know you just got that light. You dont want white corals

 

yeeah..I have only ran it for about 2.5 hours the most so far..and then actinics come on..Like today i am going to have it on from 3-530

 

i have my halide on for 11 hours a day had it running 12 to start. but its my only light source. except the moon lights that are on when the halides are off

 

Yeah, my fixture is a BEAST! it has a 150w 10k halide, 4 24w T5HO actinics and 6 white leds and 6 blue leds. So

 

i use the exact same method, if they deflate then they get turned off
