It's time for me to change my bulbs and just wondering what everyone thinks
of the xm 250 20000ks. I have the 10000ks right now.

You'll get a lot less PAR with the 20Ks, but it'll be less yellow.

I like the 20k a lot. Use one over my frag tank with no supplemental light.

They are quite blue. I run 15Ks and like them a lot. I don't have to supplement them, but I do, just so they don't have to be on for 12 hours a day.

Are you getting good sps growth

I was. I suffered a crash, and am once again returning to SPS. I am again seeing good growth, with the 15K bulbs.
