Really no input, but here's what I'm running over my 40G planned for LPS and softies. I currently have a few frags in there doing just fine. A Goniopora, Ricordia Florida, Favia and a GSP.
From 6AM to 12PM is just to over come the ambient light in the room.
12:30PM to 2:30PM is a full spectrum.
3PM to 7:30PM is a bluer spectrum with the whites, green and red turned down. I raise the brightness to keep the PAR the same through out the 12:30PM to 7:30PM photo period. I'm getting ~120 PAR on the sand bed.
8PM to 10PM is really blue making the colors pop for evening viewing.
The 17170K and 17190K are the same, the 17170K just has the UV channel set at 0%.
The light is in High Efficiency mode with max power set at 80%.
