Yea 150w is quite a lot for chaeto without a heavy nutrient load.
I used to use a 6w jbj nano glo fuge light in my biocube and it kept the chaeto growing and green. Would pull a baseball to softball amount out each week.
Sometimes it would be white right up against the glass where it was exposed to light the most.
