Clear water vs blue water. More intense RGB colors vs more intense blue color only. All of the examples other than my own are fresh water because more fresh water aquarists use the light. But I don't think it means that the color results are going to be different in a salt water tank.
The question was "Do I need PC with MH? Many canopies come with Actinics". What I'm trying to say is "No, Actinics are useless except to add blue visuals to your tank. I don't like Actinics. I like 9325K. See how colorful 9325K is. Look at the examples. I can only find freshwater examples." I know its a personal taste thing. Actinic PC supplementation isn't needed. However, higher temperature Daylight PC bulbs can add more photosyntheis (depending on whether saturation has been reached with MH alone) and help bring out visual colors that MH alone can't.
