This may be something other people are already doing but if you get a big Gatorade bottle and 1" PCV tube and some hot water you can slip the tube into the bottle. Make sure the tube is long enough to sit above the water line and then add your mysis or what ever to the top of the tube and because the tube is so long the food can slowly rain down on the colony "waking up" any polyps that haven't opened. Usualy rains down or about 25 min depending on the food
