Light (as in more to yellow spectrum [bad spectrum])


it tends to be more along the lines of the red spectrum of light that
promotes algae growth.

but other then that I agree completely with Cap. I have ran my lighting
anywhere from 6hr on/off (duel photo per day) to having it on 16 hrs per
day.

there were a few problems I had with the 6hrs on/off duel photos every day.
one was the fish seamed more stressed to me, like they needed to get X
amount of swimming done in a days time and they were forced into doing this
in 6 hrs and twice a day.. but all corals thrived and grew faster with the
duel photo periods. second and probably the worst is you end up with a dark
period in the middle of the day, and on weekends when I was around the house
I couldn't enjoy the tank during those 6 hrs like I can with it back on the
10hrs per day single photo.
