For you guys saying you want to see your fish...do you guys stay home all day? Pfff...I don't like you guys anymore. Wish I could do that! Heck, I haven't even seen my home since December...oh wait, I don't even have a home anymore.

Because the goal of my new tank was to use as little equipment as possible and I am super happy with growth as of now. As for major equipment, I have the two halides, skimmer, controller and ZEO reactor. I also have no canopy to put other lights in. Trying to keep the real sleek and clean look.

I may go back to 14K next bulb change but I doubt it.

More growth in my case is not what I am looking for anyways, its an added bonus. I am after color.

What we need is some PAR measurements on a reef in Bali say logged hourly for a year, imported in to controller hooked up to a set of calibrated Sfiligoi dimmable MH lights.

This may be a stupid question, but should there be a time of total darkness? When my actinics and MH are off my moonrays are on which gives my tank light 24/7

Would the ocean be exposed to light 24/7? Probably not. A full moon only appears once every 28 days and even then you would have to expect some clouds to block some moonshine.
