I was just wondering, I have an ada 60p nature scape, and my lights come on at 6pm and go off at 12pm. i do this cause i am generally home only by 9 pm and i would rather have them on when i am there. I have been reading about this for sometime, and there does not seem to be a conclusive answer. For some its about the circadian rythm, for some others its about the ambient light in the day which would cause the fish to get stressed.
I have been running this setup for about a month now with finnex ray2 and my plants seem rather healthy no algae as of yet just the normal diatoms which are going away. As of yet i have only 5 otos, and they seem fine as of yet.
What do you guys do and what are your opinions on switching on the lights in the night instead of day.
