light schedule

[cartoonbear]

Later today I am going and picking up my new lighting. 8 x 65 watt PCs. I am interested in how I see some tanks set up to mimic the movement of the sun and I also thought that It would help keep some of the heat from the tank down. But then how should I rig this up with this many lights?

I was thinking having the blues come on at 6:30am, then the whites at 7:00
am, then the whites off at 7:00pm and the blues off at 7:30 pm. But then that wouldn't keep the heat down too much. Would the loss of the constant light be bad for any corals? Would it slow down growth?

Here's the light schedule I use on our tank, in case it helps any...

8am actinics on / moonlights off
10am daylights on
7pm daylights off
9pm actinics off / moonlights on

IMO, 12 hours of full-on light is too much. With the above schedule, we don't have heat issues with our PC lighting (only 4 bulbs, but also a slightly smaller tank -- 90g). By that, I mean a fan blowing on the sump is the most I need to keep temps good during the summer.

I'm not sure I understand your question: "Would the loss of constant light be bad for any corals?" Please clarify.
