Lighting 180G (72x24x24)

Great! Then I maybe able to extend my Actinic's life for a bit longer. Anything to save a few more pennies for those "GOTTAHAVEIT" DAYS.

Oh here I am suggesting T5 bulbs for actinics. *slaps forehead* You don't have nearly the amount of choice with the PCs. I agree that the Phoenix look great on their own, so you wouldn't need to run the PCs all day, just the dusk/dawn. Fwiw, your tank should get 12 hours of light a day, with 6-8 of those being high intensity, so you can run your halides for 6-8 hours, and then the PCs before and after to make up the 12 hours, with say a 15 minute overlap to make up for halide warm up. Does that make any sense? Maybe not...ok something like this:

8:00 PCs on
11:00 halides on
11:15 PCs off
16:45 PCs on
17:00 halides off
20:00 PCs off

That way you will save bulb life, and electricity.

Gee thanks for really spelling it out for me. Sometimes it is easy to assume a newbie may know what you are talking about. I will be doing that when I do my light changes.
