I am getting ready to change out my MH bulbs, I have always used 2 175W Ushio 10K bulbs with a combo of 206W PC actinic over my 55gal. I like the look and my coral do well with this setup but I was thinking that I would like a little more blue. I have done the search thing and read everything about the xm bulbs, the only question I have is how blue are the 20k bulbs, with the pc setup I already have I don't want it to be too blue, but I would like a little more blue then it is now, and how to the 10K xm compare with the 10K Ushio? Thanks for your help in advance.
