Dosing recommendation for Clams and photosynthetic corals (Hard corals etc.):Mix Ultra Clam and Ultra Min D to a stiff MASH. Add as much Ultra Min D until a small (1-2 mm) supernatant forms and leave standing the food over night. The next day the supernatant should have disappeared. Now add more Ultra Min D until you have a small supernatant again, and leave the food standing for a few hours. You can store the food mix for about a week.
