I think the pre-programmed ones are fine but nothing special. I say find a visually appealing mix for you. Then share it here and I (or others) can make suggested edits. I like to limit UV to 50 or have it up during peak hours and go down at some point as to not melt a hole in the lens. Violet I also like limit its upper strength for peak hours for the same reason. Royal blue and blue can be kept at around 100 for most of the day without an issue. Red and green can be set at whatever you'd like. Don't worry about red and algae, its nothing compared to the blue light. The same goes for the white channel. I like a bit more white, red, and green for the fish to have a better visual environment Keep the light at about 13 inches off the water. You eventually need a 2nd light as one only covers roughly 18x18 - 24x24. Avoid running the light at its max power for long periods of time.
