Hi all,
I purchased a 2nd hand Orphek Atlantic v2.1 b fixture, I am experimenting a bit with the intensity of the 4 channels. When I Google for information on what other people are running at, I have found little information, so trying to get a thread going here specifically for this light.
I was running the 4 channels at 75, 100, 75, 75 and I measured my PAR to be around 250 - 300 at top of my rocks with Seneye.
I have noticed that the intensity doesn't drop off dramatically it seems the lower you go in the tank as I have seen with other lights.
But my coral are struggling a bit, paling and closing up, so I have lowered to 40, 100, 40, 40. I like the blue look, so I have the whites and 3 and 4 channels decreasing towards the evening. I will see how the corals respond at these settings.
I am interested to hear what others at at and their experiences.
Thanks
