I do 9 hours total. Sometimes longer if they want to watch a movie ; )

I start their virtual day with 1 hr Actinics, 7-1/2 hrs day and Actinics
back
to Actinics and then the rest lunar.

I also do a reverse photo period with my refugium. (about 10 hours)

At one point I was doing 12 hours, but I had a small problem with
cyanobacteria.
Cutting back on the light and nutrients I've found a pretty good balance.

General questions for those that try to similiate a 24 lighting period.
what do you suggest lighting times for a light set up that has the
following lights and can be placed on timers for best lighting results?
what if any time over laps for the different lighting?


10,000 k day lighting
actinic blue 03
