I got my echotech diffusers for my radions yesterday. They were easy to install. I didn't think I was going to see much difference when I turned them on but there was a very noticeable one, at least to my eyes. The colors looked pretty much the same ( I have lousy color vision) but the lighting as a whole looked more like T5. Softer. more diffuse with a different kind of shimmer. Looks good. I will post updates as time passes and the coral responds.
