Lighting Question

My fish seem to freak out when the light(flourescent) is turned on.
In an effort to reduce any stress...
Are there any manufacturers of lights that turn on slowly???

Switch on the room light first before you turn on the aquarium light.

I'm ready for the pressure.
The drama and the pleasure!
If there is one thing I want to see here, it's HUMOR.
I believe I can fly!
I believe I can touch the sky!
I think about it every night and day!
I stand in awe of my body.

Sorry, but dimmer switches should not be used with flourescent lighting.
Most wont work this way at all and i believe it is bad for the electronics inside the light.

The ambiant light option is one of the best. Any window that will light the room some, or some lights in another room will lessen the shock of instant light. My neons during the winter would kinda freak out and I actually saw that they kinda sleep when the lights are out as their color faded and I saw the color change if I turned the tank light on in a totally dark room. Anything that lights just a little will help with the transition.

As for dimmers, you are right ttmmm, you should never use a dimmer for flourescent lighting. It can cause fires and will burn out the light ballast and lights in short order.

Leave the room lights on for about 20 mins before turning fluorescents on. I myself don't do this, I open curtains.

Tanks: 40 gal FW setup, 10 gal Reef tank.

Thanks for the advice everyone!
Thats exactly what makes this forum so great 8)

I've decided to use a free-standing lamp right next to the tank. I'll put a dimmer switch on that lamp so I can gradually let the light wake everyone up. This new lamp will also be lighting the new 10g tank I picked up today which will sit right beside the 29g.
I've seen almost all of the Guppies with their tails stuck down into the gravel in the morning apparently sleeping. The shock of turning on the flourescent sends them all into a panic then they hide in the upper corners for an hour or more.
I hope to reduce the occurence of diseases by reducing their stress in any way possible

I found this little lighthouse the Wife had stashed away and it works just great!
With just the lighthouse turned on the 29g lighting is perfect for nightime 8)

LOL...I had to buy the 10g tank and make the lexan cover for the light to sit on

if you want something a little more "professional" looking, just go buy a small incandescent strip light (10-12 inch one with 1 light socket) and get a blue or red bulb. You can turn these on first and they won't be too extreme and then turn on the flourescent later. You can also use the small incandescent at night to simulate moonlight.
