The razor is what I almost got. The only thing that got me to go with the AI Sol was I saw it working at the LFS and was very impressed. The salesmen put it through its paces. The razor legs can't be adjusted up or down, so it is a "fixed lighting element" which isn't really an issue since it has a built in controller. The Kissel would look great and is a very nice light....would one be enough coverage - I don't believe it would which means you would be spending more than if you got the razor or AI or the Maxspect P-Series. I don't think you can go wrong with any of the ones you are looking at, as they all appear to be comparable for the most part. Again, my only concern about the Kissel is that you probably would need two, especially if SPS is in your future for the coverage of the tank. Just my thoughts, but I am no expert on LED....just learning it all. I was up to speed with the MH and T5, but the LED lights are a new learning experience for me.
The tank progress looks great I really like the entire look - tank, aquascape, MP10, stand. Great set-up.
