Hello everyone! I realize that I could probrably just read through a bunch of these threads to find this answer, but I am lazy tonight, so I appologize if this question is asked often.

I am interesting in finding a lighting solution that can be 'hands free' for my two 55 gallon tanks, such as a timer, only with the option for the lights to slowly fade out at night and slowly come on in the morning. I am asking if there is such a thing because I have a tank that gets a lot of light through a window and the fish in this tank are not as skiddish as my other two tanks and I think this may be because it isnt as shocking to just all of a sudden be engulfed with bright light and vice versa. I also use some of those smaller 'accent' lights you can buy in different colors in a tank that holds some eels and it is great because I can see them out and about when the main lights are off. I would like to forgo those though because they are always getting covered up in algea and I dont want to keep promoting the growth of it.

Is there anything on the market that might be able to create this effect with my existing hood lights or would I be required to buy a new system? What I have now are just typical hood lights with the half cover, half openable cover and these are not special bulbs at all, just florecent tubes like in a shop light.

Thanks for any info or ideas!
 
If you have flourescent lighting you're out of luck. I don't think they recommend that you put them on a dimmer switch. I don't think they'll work that way. If you use icandescent lighting you'll be able to dim the lights manually......not sure if they make a timed dimmer......
 
The reason I want the lights to dim on and off is because it takes my fish a good half an hour or so to come out after I turn the lights on in the morning. I think they get startled from the lights suddenly popping on and off. If this is a bad theory, then can anyone suggest ways to avoid this? This has been happening for around 8 months now and so I do not think the tank will 'grow out' of it, but like I said, I could be wrong.

You can get dimmers for certain compact flourescent bulbs. I have a setup on my 135 that has CF with dimming ballasts.

No, I think you're right Tommy Gun. That's why I either set my timers to turn the lights on AFTER the sun has been out for awhile, or leave the room lights on after lights out. That way, the change is not from 100% light to 100% dark. I think it makes a difference, especially to skittish fish. This way it's just more natural, too.

Those are my ghetto solutions to the problem. The dimmer would be a fancy way to do the same, but not on this student's budget! :)
 
I eleminted that problem when I installed moon lights in my tank. My fish were more active the next day.

ooh, cool! I've thought about getting those, too, so I can watch my night feeders in action. I'm too poor for the whole fixture, though, and can't sacrifice a bulb in my overhead light as I have live plants. I'd probably go with the stick-on 1W ones, if anything.

I wonder why they were more active the next day?

:cool: Great minds tend to think alike. (Hi "P") My timers are set similarily. The lights come on after sunrise & go off just before sunset. Now of course some days are brighter than others but no extreme light or extreme dark 'shock'. The 'lunar' lights in my C/P strip keep it frm ever being completely dark & also give me a peek at my 'cat'. http://www.bigalsonline.com/BigAlsU...484x65wattpowercompactlightstripw2lunarlights Not positive but I don't think you can put a dimmer on a standard flourescent. plah831's "ghetto solution" (I luv that :idea: ) is the next best thing!!
