Getting corals to pop and glow is really easy under the razor. As far as I am concerned, there is nothing wrong with the spectrum for either the visual nor the growth case. I do tend to run a bit more whites in the afternoon (when I am most likely working and away anyways), and then by the time I am coming home things are blue'ing up nicely.
The whitest I run is channel A at 100%, and B at 80%. I like the visual difference of a more 10k look, the variation, but don't particularly like how the corals look. I personally find the best color balance of about 1/3 more blue (B) compared to channel A. So if B is at 90%, my A is at 60%. To me (YMMV), this is the absolute best color, colors look great, but not insanely blue yet. I achieve this by going from that 100(A) 80(B) point to having my next point have B at 100% and A down to 60% (which I know is beyond that 1/3 mark I mentioned above, but keep in mind it's transitioning to that point steadily). By 4pm, things are absolutely perfect. From that things for me tend to progress more on the blue side as the tank dims into the evening.
When I said I like the color of the kessil more, the reason being is it's slightly more _blue_ where the razor is slightly more _purple_. Honestly you would never be able to tell unless they are side by side like mine currently are. I tried to take a photo to show the differences just now, but even my camera could not pick it up well.
I have the wider lenses but don't use them. They reduced the par too much, and did not really help the shadowing to any significant degree. I felt like I was getting better results with the stock lenses. Adding the kessil fully fixed my shadowing issues, as it is forward, and angled at about 20deg to give a different angle to the incoming light.
Not sure if that helps. Honestly you will need to tune things to find where you like it, and where the corals like it. I personally did not use their built in curves at all. I just thought I would let you know how I tuned it for some success. Feel free to let me know if you have more questions.
