Acro's need time to adjust to the new conditions and should be on the bottom of your tank to start. After a week or two, you can move it up a little higher, then another week before you bang it under the light. Also check your ALK, 8dKH to 9dKH are good numbers. I take about 4 weeks with new acros before they reach their final spot.
