Photoperiod Convo

[Mike]

270 gallon SPS reef

LIghitng: 2-250 watt XM 20K's in lumenbrite Mini's on ice caps. 2-400 watt 20 Radiums in Lumenbrite mini's on lumentek ballast.

Photoperiod control via profilux controller.

1st 250 starts up at 11am-7pm
2nd 250 starts up at 12pm-7:30pm
2 400's start up at 2pm and off at 9pm

There is about a 5 hour period where all the lights are on together. I wanted to avoid running them all together all the time. I do believe that you can have too much of a good thing when it comes to lighitng.

I started using lugols as well to aid the corals with making (sun-screen) and dose 8 drops every Sunday of the Brightwell lugols.

I use to run my lights 12 hours a day but since placing multiple MH over the tank I can still enjoy viewing the tank while cutting down the exposure of the corals to constant high noon.

Thanks Mike, I learned something new from you post! Iodine/lugols aids in protecting corals via producing "sun-screen" good to know.
I've never dosed iodine other than when I see a shrimp or other invert that needs to molt. I'll add a little Kent Tech-I.
