I have the panorama pro module on my five gallon nano. WAY too much light for that tank. I could probably grow a little five gallon forest of sps in there. I will say that the light is very white overall. Even the "blue" is more white than blue, so keep that in mind if you like a more blue balance. I have heard the new panorama module that comes with the timer is a little weaker than the other ecoxotic lights, so I went with the Orbit Marine for my IM 30L. I don't really have any desire to do much more than softies and lps, so it will be perfect for me. I have seen people supplement with kessils (sp). You would be safe buying two of the lights and would still have the functionality and light output you need without spending 600 bucks. Good luck!
