 Topic: Lighting schedule
Posted: October 17 2007 at 11:24pm |
I was wondering what kind of lighting schedule other members use on
their tanks. I was reading over on another forum about lighting and I was interested in how a lighting schedule should be set up.
From what I read, aome people say there should be multiple timed lighting periods.
For example:
9pm-8am - moon lights
8am-11am actinic's
11am-7pm MH
7pm-9pm actinic's
or should you have something where your moonlights are on at night and your other lights turn on at the same time to run during the day.
Which is better any why?

That's an awesome question, I was wondering the same thing. I do:
Moon lights - always on
8am-11pm actinics
11am-10pm MH

Here's my lighting schedule:
Moonlights - Midnight to 8 AM (8 hrs)
Actinics - Noon to Midnight (12 hrs)
Halides - 1pm to 9 pm (8 hrs)
Fuge light - 6pm to noon (18 hrs)
You may notice that from 8AM - noon no lights are on except the fuge light
I do this to give everything a little "rest" period w/o any artificial light - just ambient room window lighting

BTW - you should turn off your moonlights when the others are on... not that it hurts anything; just that it can't be "seen" anyway when other lights are on - and (eventually) you will burn out the LEDs after so many continuous hours.
Also, more than 8 - 9 hours of MH is probably 'overkill' when you have other lighting available. Plus the MH lights are the 'heat makers' and 'energy hogs' in your tank

I'm not really worried about the LEDs burning out, they last just about forever. I am planning on putting them on a timer though since they run off a transformer (waste of electricity).
The MH sure are heat makers! Wouldn't mind cutting back on MH time, we'll have to see what people have to say about it. My MHs are getting a little older so I think I'll run them a little extra untill I replace them!

It depends a lot on your preferences. Conventional wisdom states that 6-8 hrs of MH is enough for coral photosynthesis; actinic is to create sunset and sunrise. Lately, several people on reefcentral use MH only for 4hrs a day and still have good results. So it boils down to what you like: whether you want to conserve energy AND avoid overheating the tank; whether you want an extended period of viewing times, etc.
My schedule is:
Actinic on 10:00, off 23:00 (13hrs)
MH1 on 14:00, off 21:00 (7hrs)
MH2 on 14:30, off 21:30 (7hrs)
MH3 on 15:00, off 22:00
That way I have a lot of viewing time; a good amount of sunrise and sunset and don't spend way to much electricity on MH.

Nah, they are all 14k DE Phoenix bulbs running on Icecap electronic ballasts. My tank is 72'' long, so I have 3 MHs. I stack them up so that the fish don't get scared when suddenly their environment goes from dark to bright and vice versa.

I am not all that tech-savvy. I use good old industrial grade timers to control them.

I totally agree with Dinhkim...personal preference is a very big player here! My schedule on my 125: 3 160W URI VHO Actinics 9:30a-10:00p 2 175W 14k MH 10:30a-9:00p Refugium lighting 9:00p-9:30a I'm thinking about cutting down on the MH by about an hour or so for energy reasons, but now that it is getting colder...maybe not.

Thanks for all the great responses. I think I need to make some more changes to my lightng system. I have all ways just had my moonlights on at night and my /mypc lights on at the same time durring the day.
I will need to chance a little wiring to allow me to alter the schedule more, but I guess that will be todays project.  |

I have found it is nice to have some lighting in between actinics and MH.
I use VHO for the in between times.
For example I run:
6AM - 10PM Actinics
8AM - 8PM VHO
10AM - 6PM MH1
11AM - 4PM MH1
No matter what you do I have found you want lots of options.
It is best to have the lights on seperate transformers/timers.
I also find the VHO is nice to have for tank maint times.
I don't like having the hot MH running when I am trying to clean the tank.

I have set a split actinic schedule with 8 hrs of MH in the middle.
