I think the problem with adopting settings from some other user is that there are way to many other variables that make that particular user successful that may not work for you. When I just recently switched to the AI Hydra 52 HD and I researched the "best setting" I ended up choosing to go with science and facts. Someone else did the work already, I am just riding their coat tails.

I'm using SPS AB+ as described on page 7 of the pdf ( page 5 of the actual doc ). My fixtures are not 24 inches above the water like the ones in the experiment, so I have adjusted my intensity equally across all channels, keeping the exact ratio as the original SPS AB+. If I reduce one channel by 10%, I reduce all channels by 10%.
I bought a cheap $10 Lux meter so I could dial in the intensity I wanted without worrying about what par and pur would be.
