well its time to change bulbs and im undecided i want good growth but better colour then my XM 10000k. Its for 250 watt. Whats your opinions?? i cant run any extra lights like actinics because i have no space to do so. This is a PFO pendant. Im thinking maybe the XM 20000k??? anyone have one??? whats your thoughts???

I liked my 20,000K XM bulbs, but things do appear pretty blue. Under them I got great coloration, growth seemed to come in waves, rather then being constant all the time. Overall I loved the color they brought out in my livestock.

were you running actinics or suplimental lighting as well or just the halids?

Just the MHs for a long time, a year. I just stepped up and added in T12s as supplimental lighting.

were you growing sps?? and if so how was growth???

I had SPS, clams, and some LPS. Growth was pretty good, although it seemed to happen in waves, at some points I would see great growth in my SPS, and then there would be a lull in which nothing seemed to grow. My clams continued to grow constantly, and I didn't see any lags. Most LPS thrived, although not everything grew that much.
