I currently have the K7 mini on my 15 gallon cube. Great light for my nem setup. Im upgrading that tank to a 40 gallon and would love to get the K7 pro or even a second K7 mini.
The first review I read on the Noo-Psyche's site for the K7 Pro III is my exact situation. I just upgraded to a 75 gallon for my reef tank and I am currently running the 2 AI Hydra 26 HDs and would like to put something between them. The review by Stephen said exactly the same thing and that the K7 Pro III would be exactly what I needed.
