Does anyone simulate sunrise and set? I have a string of blue led Christmas lights, 3 curly cue compact florescent, and a 4 foot shop light on my 75. They each are on timers to come on in half hour increments. They go off in the reverse order. I like to watch the evening and night behavior of the fish. Kind a strange I know. Guess I need more tanks to occupy my time.

I do this with my Marineland plant LED. The fish seem to know whats going on and the plecos start to either go in or come out.

I would love to have LED for my tank but I am on a tight budget. If my stuff isn't 30 years old it is homemade. I am very much a low tech kinda guy, I need to update things a little.

Great Idea Chris!

I've thought about this, but never acted on it....

What is the time spacing between each light?

I'd love to watch my fish wake up and go into night mode and it seems pretty simple which I like!

Thanks for the post...

My 4 foot light is off @ 8:00, 1st compact florescent off @ 8:30, next cf off @9:00, last cf off at 9:30, blue LED Christmas lights off @ 10:00. I forgot to mention earlier that I also have a solar LED path light with a light sensor on it turned upside down. That gives a soft moon like glow to the tank. There isn't enough light in the tank to truly charge it so after few weeks the light gets dimmer and dimmer kind of like the phases of the moon. Then I take the battery out charge it and the moon is full again.

This is my favorite part. This is really clever. ThumbsUp
