I was with iwasaki 250 when I change for the radium even reduce light ing period to 4 houre a day and get it up slowly over couple of month and some coral have take very long time to focus on the radium some even could just not do it candy cane is almost ded after 6 month 
 
green frog spawn just start to look good 1 month ago  even a brown clam have slown is grow for couple of month but now it is ok  
 
On the other hand all hight demand coral blue and purple clam love it and grow like mad and improve in color like notting els could do it  
 
to my eye I could tell  they are more brighter than my saki and all people came home  tell  the same you allmost need sunglass to look at the tank  8)
