Just wondering what intensity and/or schedule you are running with what tank depth.

Right now I am running the Coral Lab at 90% intensity, so on the graph it peaks at 54% intensity. Lights are approx. 9" above the water line and tank is 24" deep. Tank is a standard 120 4x2x2'. The tank is adjusting to a few new changes, I know, not a good idea. I am going back to biopellets and HC GFO plus the new lights. I have lost a lot of SPS and some others are not looking too good. Wavy shit are not fully extended either. Am I cooking them or choking them out?

I'm not sure if I have just been doing it wrong the whole time, but I adjust the yellow slider bar for my overall intensity. I have mine at 40% right now, at about ~11". At 40%, when I hover over one of my set points on the graph, the intensity shows 26% max in the little box that pops up (not really sure what this means). I bleached and killed a few corals when I moved and it was only at 55% I believe.

The Lower % when you hover is of the overall fixture. The 40% on the side is overall of your schedule

Radions are powerful lights. When it doubt use the acclimation mode.

Mine run at about 10” off the water. I run the coral lab ab program at 55%. And that is plenty for sps. I would say you were cooking them. You can slowly ramp them up to 100%, but slowly! There are a few people running them at 100%. And their corals look amazing so it can be done. Good luck.

I am running mine at 75% overall with their Sps AB+ schedule with a slight tweak in the evening so I can enjoy colours. My lights are 9” above the water surface. My rocks are stacked 12-14” below the water surface so overall the corals are about 22-24” away from lights. On top of my 3 radions I also supplement light (3 hrs daily) with a dual strip of T5 HO. Corals are all happy and growing. Last weekend I borrowed apogee par meter from Canada corals and I tested the par at various depths particularly when my radions were at 75% + the T5 were ON as well (so max light output). I have attached the picture to give you an idea of what pat readings you can expect.

Now that is some great information. Thank you. I wish I had someone around here to borrow a PAR meter from. That would be ideal for sure, but this gives me a good idea on where to work off of for mine until I am able to get my hands on a meter. Thank you @TheGreenStag

You are welcome buds. Yes Radions are strong they made them to match up the spectrum of a 250-400 Watt Metal Halide. Often people post their intensities they run their radions but what is more important to know is how shallow/deep their tanks are, placement of corals from the surface as well as from the lights. I think you should start at 60 and gradually go higher every week until you find the sweet spot. I have seen your tank on YouTube. Mine is 75% because when I go any higher corals show signs of stress and it was also proven further when I got my hands on the par meter. Ryan at BRS in one of his video mentions the sweet par rating is between 250-350 and if you can see from the above pic most of my corals are in that range. Sorry for the long boring post
