Coming along with my rock design. DT under Orphek Lighting:
I made a small change a couple days ago that had a huge impact on the look (whiter, less blue overall) and the corals didn't react at all so I think this will be my final recipe since I love the look. Or not... I may raise channel 1 even higher and lower 3 to get an even brighter whiter look. Anyhow, here's what I have now:
Ch1: 82% with a two hour ramp morning and night, ten hours total (6@82).
Ch2: 100% with a one hour ramp in the am and 90 min in the pm, 12.5 total.
Ch3: 42% with one hour ramp in am, 2 in pm, 11.5 hours total.
Ch4: 32% with 90 min ramps on each end, 10.5 hours total.
Sorry for the delay Nick. The start times are not all the same- channel one starts 2.5 hours after the the first [channel 2] lights come on. Chanels 3 and 4 start 2 hours after first light.
The look of the tank and corals seems to be much better now that channels 3 and 4 are greatly reduced (38/32%) and channel 1 is greatly increased (90% now). It took me a long time to get around to these levels because I incorrectly thought UV should be kept low-ish and the whites [3] at high settings would be best. Now that I've ran basically the opposite it's obvious that the corals are happier and the tank looks great with high channel 1 and low channel 3 settings. I may even bump channel one all the way to 100 to see what happens.[/QUOTE
Thanks Greg that's useful to know. No point re inventing the wheel if somebody else has gone through the learning phase to establish some settings. I am going to set mine to the same how many months did you take to get to these settings and what adjustments did you make at each change ?
Thanks
Nick
You're welcome- I did shorten the photo period by one hour.
Still seeing pretty happy corals across the board in terms of polyp extension, coral color and growth. Clams, LPS, mushrooms and toadstool leather all on the sand are doing well, as well as SPS and Euphyllias higher up.
You got me motivated to snap a few shots
Hi Greg,

Woow... what a results!!! :dance: Cool and indeed inspiring.
