Razor 120w or 180w?

It is going to depend on what you are trying to grow. I grow LPS and SPS in my small tank.

I run a maxspect 130w razor over a 35 gallon tank and I feel it is not enough. I find that with only the 2 banks of Led's it is creating way to many dark spots and the corals are growing up but being shaded within. When I move my tank I will be adding a couple of T5's to supplement and reduce the shadows.

On the 180, the light might be a couple inches longer then the tank but the banks of led's are set back well from the edges.

I would go with either the 180 watt maxspect razor (remember you do not need to run the lights at 100%) or preferably go with the 130 and supplement it with a couple T5's.
