Roger,
The bule and royal blue channel runs for 8 hours at 50% with a 1/2 hour ramp up and ramp down. The white channel runs for 7 hours with the same intenisty and ramps. I also run the royal blue channes for an aditional 6 hours at 3 % for moon lighting for the rest of the night. so there is no light for 10 hours.
I have about ratio of 80% LPS, softies, and 20% SPS and three clams what ever catagory you would put them in.
The only other thing you may want to know is I have mine mounted 8" off the waterline.
