This is exactly what i do. Turn the flow off and feed every mouth. Seems to really make them grow quickly. I have been collecting a bunch that last year and am going to grow a sick acan rock...i hope.A little trick is to make some reef roid paste or gel consistancy. Get a dental flushing syringe with the curved plastic tip, cut a little off so you can suck it in and feed each mouth when you have time. Acans are my favorite.
