I use four teaspoons of the Oyster Feast and then dilute it with four or six tablespoons of tank water. I squirt some around the tank before feeding time with the pumps off. Then I feed the fish some mysis and wait for a bit. By that time the feeding response is pretty jacked for all the corals in the tank, and I target feed the SPS with the diluted Oyster feast two or three more times before everything gets turned back on. Meanwhile I am feeding the fish and also target feeding the LPS with the mysis. I like to take my time and do this with only my blue lights on in the evening. It seems it must take them a little longer to eat, so I shoot for an hour and a half with plenty of the Oyster Feast in there for everyone to enjoy. Best all around coral food in my estimation! Well worth the money.
