I started off with using "Jonathan's Graph", which is a simple bell curve style lighting schedule. This is supposedly one of Ecotech's employees, though I have no confirmation of such personally, but should be easily obtainable as I google searched it to get my hands on it years ago.
As it stands, I have my Radions between 10-12 inches above the water line. I run them at 60% power max. With that, I still have SPS
almost in the sandbed.
When I set acclimation mode, I put it down to either 45-50% power for any period of time from 3-5 weeks.
I don't know about the pro models, but I am under the assumption that these come stock with their 90 degree optics...be it TIR or not. I have swapped these out for the wide angel lenses to address shading issues as my SPS
colonies grow which has left to a great looking colony up top but a skeleton below it after consultation about this issue with Ecotech.
