Im waiting for mine(checking tracking every 6 min.:D)
I set my ratios by eye, or more blue for deeper water corals. I set the overall intensity with a lux meter. Esp in acclimation.
Im going to start mine at 18,000 lux and go up from there for approx 25 30 days till Im at 40,000.
currently I have MH+led @38,000lux.
