Thank you - bwhit1406
So after further research as to what I want my SPS to be in this tank - I am looking for great color.
So one of the advantages of the Radion's are you can change kelvins to accomodate your goals.
I have changed my photo period to be dominantly 20k - 18k.
11am to 12pm the lights turn on and gradually reach 20k.
From 12pm to 4pm the lights ramp up to 18k.
From 4pm to 5:45pm the lights ramp up and peak at 16k.
From 5:45pm to 7:30pm the lights ramp down to 18k.
From 7:30pm to 11:30pm the lights ramp down to 20k.
From 11:30pm to 12:30am the light ramp down to off.
I want to induce a natural photo cycle however I want to keep the higher kelvin to encourage more so color and a bit of expedited growth.
Note that all the higher end retailers that sell SPS samples keep their species at 20k. Granted that they have huge colonies so I guess when you get to a point - the 20K slow growth color rich kelvin is best.
The Radions really are powerful - especially when you install the TIR lenses.
You can easily bleach your corals if you aren't careful - but through my experience playing around in the 14k to 12k kelvin range, the corals did lighten up but they also demonstrated explosive growth.
So what I am saying is that you can't always have it all. The only reason I have a peak of 16k is to experiment.
I am starting to see the first gen radions sell in the $400 range, if you have it in your 2013 goals - deff go for them. Very satisfied with the Gen one units!
