Tell me about your lighting period
 

Mine is halides on for 11.25 hours. .25 for the warm up of the bulbs.
Actinic is on for 14 hours. 2 hours before and 1 after.

Actinics for 14 hours, 10000K PC's for 12 hours, and 175 watt MH on for 6 hours. oh and moonlight for 12 hours


Steve

The way I look at it .... in the tropics, daylight is darn near perfectly 12 hours any day of the year. So my tanks are lights on for 12, lights off for 12.

50g: halides for 12 hours
75g: halides for 10 hours, VHO for 12 (currently no VHO thanks to the zap!, however, but will return to the 12 hour cycle when I have time to look at it)
20g: halide for 10 hours, no dusk or dawn, but gets residual light from other tanks/plant stands/etc.

But you already knew all this, so I'm just wasting electrons by typing it in. ;)

No it's good info keep it comming.
I do have a purpose for the info once we get the only 12 people that actually post on canreef's answers to the question. :wink: :P

Any of you lurkers want to tell me about your lighing period :D

2x250W Iwasaki 10hrs with an hour of 4x110W actinics on either side.

My center 400 is on for about 11hrs. and the outside Radiums for about 10hrs.

Hi, my name is Brad and I would like to reply. My actinics are on 14hrs, MH are on 12hrs.

actinics 14 hours
DE MH250 10 hours
moonlight 10 hours

Mitch

I have my actinics on from 6:30 am till 9 pm (stays on longer as my wifes parot really likes the actinics)
my 175 W Turtle basking light from 6:45 to 8:15 pm
2 40 W flourescent rom 8:00am till 8:30 PM
my 1000W MH freshwater grow light 08:00 am to 5:30PM
2 110 W VHO from 08:30 am till 07:30 PM
175W Mh from 08:30 till 08:00
and
Ok this may sound stupid but...
on full moon nights I leave the actinics on all night.

If you save SAD...seasonal affected disorder....a couple days of sun tanning in my basement wil fix that up :D

Both tanks run a 12 hour cycle, gradual increase/decrease. A small red night-lite in 60g canopy and a conveniently located streetlight outside gives the 90g a "simulated" moonlight glow... :roll:
I read somewhere that "strange people" become more active during the full moon cycle. Fortunately Ross has dismissed that theory... :wink:
I wonder if the city would consider synchronizing that street light with moon cycles :? I'm afraid to ask.
I think I know where you're goin' with this one so I'm probably not included in the 12 required responses... :wink:

Actinics 12hrs
6500K 10hrs
10,000K 8 hrs

1x250W Iwasaki - 8 Hours
2x110W Actinics + 2x40W 6500K NOs on an Icecap660 - 12 hours

I will be extending my MH period to 10 hours very soon.

Actinics 12hrs
MH 10 hours
Mooning by request.. :D

I only have PC's. On from 9 am to 1 am usually (15 hours).

Yay I get to be person #13!! Woohoo! Who knew eh? :P


My tank has 2x250W Iwasakis on 12h/day. Actinics gave up the ghost. An interesting electrical problem. Apparently my hood carries a charge :roll:

Christy :)

Well not including me you are 13 but including me you are 14 :P
OK so we have heard from most of the regulars( I thank you all for the info) now lets try to hear from some of the lurkers that never speak :D
Keep them comming.

12 on, 12 off, Jonny. All times stated are approximate. Does not include GST.

:wink:

All 3 tanks :

Actinics 12hrs
Daylights 10hrs

:shock:

my single attinic-14 hrs
and the second attinic and single powerglo 18,000k-8 hrs
3 hrs dawn and dusk

I share Tony's philosophy on the 12 hour daylight:

- 2x 40W NO actinics 12 hours.
- 2 x 175 W 10,000K 9 hours.

Hi. You only have actinics? Marine-Glo is also an actinic. Did you mean that you have power compact fluorescent lights or VHO lighting instead of actually 3 actinics? That would be very blue otherwise.

The wrong glo
 

Hi Sam, yep sorry about that-it's a daylight powerglo tube not a 50/50 like once stated. I run a total of 90 watts-that's it! And things keep growing and growing. I was considering to upgrade to pc's, but I thought if things are working fine-then don't fix em.

2 x 96watt PC Smart lights on at 6:30 am off at 9:00 pm......

I MAY.. thats a big may change my plant room around and put in a 135ish tank. I have a 400 watt MH and I might put it over the tank with a 10,000k bulb and move the shelves I have the Orchids on, I already suppliment their light needs with fluorescents. If I do that the MH will be on about 13 hours a day.
