I generally feed three times daily, with each feeding divided into smaller portions. Mornings, everybody gets a cube (from a rotation of SF Bay Saltwater Mix, Calanus, Mysis, Angelfish Formula, Formula One, Formula Two, Capelin Roe, etc...) and a chunk of LRS or Rod's - again, a rotation of five different blends. This gets melted in a cup of RO/DI, and poured into the return chamber of my sump in three or four portions over an hour or so. On days when I can get home at lunchtime (weekdays, working closer to home) a shot of pellets, followed up by a sprinkle of flakes. Evenings, since I'm currently treating a group in QT who've shown some white, stringy poop, they're getting the same food as the morning meal, but with Selcon, API Quick-Cure and Seachem Focus dripped/sprinkled onto it, and without the RO/DI. After it melts, I'll drop in some pellets, mix thoroughly, wait ten minutes or so, and then drop dabs of it into the return sections of DT and QT with a spoon, three or four times over a couple of hours. Some days, I'll thaw out a mussel (QT) or littleneck clam (DT) which I'll hang on a clip in midwater, along with a half sheet of nori. They'll snack on that throughout the day - for as long as it lasts . . .
