Well I do feed a bunch!! The more you feed your acans the faster they will grow. I use frozen Mysis and Ocean plankton direct with a pipette about 3x a week. I thaw and rinse the frozen cubes with a small strainer before I feed to eliminate the waste water that is in the cubes. I noticed other polyps around the one I was feeding would close when they came in contact with the dirty cube water. This enabled me to get more food directly to each polyp and lessen the amount of waste in the reef. Hope this helps.
