Lighting time

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
lunar led spot lighting

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.

I have a power compact setup
2 96w 10,000 K daylight
2 96 w Actinic blue 03
and 6 3/4 w lunar spot lights

Each light can be set on a timer

12 hours is closer to the tropics, so that's what I have
always done. But that's not to say that one can't do it
for 9 hours. Here at the store, 2 days a week they don't
get any light since the store is closed, and on another
day they only get about 4 hours of light, and it does not
even seem to effect the corals.

10,000K what? CF? VHO? MH?

actinic blue 03

same as above...

lunar led spot lighting


The answer you seek will vary depending on what you have in the tank,
and the size of it.

I do very well with my 20 gal nano my having my single 20000K MH on for
18 hours, off for 6, and no lunar lights at all. But it's somewhat
crowded tank - about 1 sq foot of asstd zooanthids, some xenia, 2
tridacnids, numerous snails, 3 conchs, cleaner shrimp, some hermits, 2
ocellaris clowns and a yellow tang (yes, I have a yellow tang in a 20
gal. I swap him out at LFS when he gets above 4 inches, and get a
smaller (1-2 inch) one) Point is I generate a lot of nitrate, and have
plenty of grazer to take out the resulting algea if I use a lot of light.

If things are crowded, and you are getting a lot of nitrates (ie:
anything above 10) you probably want longer daylight times to boost the
algea growth.
