20k and sps
As you may or may not know, I'm setting up a 20g SPS tank. The 175w MH retro kit I'm getting comes with a 20k XM bulb. I really like the color, it has a nice blue shade to it. Not as yellow as the 10k. My question would be, is this light going to work? I have no supplimental actinics running with it. Just the MH.
Thanks
Marty
