1 - 2 teaspoons per 100 gallon tank per day. Add to a high flow area of the tank, or for target feeding, premix 4 parts tank water with 1 part Oyster-Feast. Because different captive reef systems process nutrients at different rates, we recommend that new users start with half the recommended dose and slowly increase to the full dosage over a 1 month span. When you feed your corals other Reef Nutrition products along with Oyster-Feast, you can take advantage of this strong feeding response by first adding the Oyster-Feast and waiting a few minutes for the polyps to open up to feed before adding the other feeds. Note that color variations in this product are normal. Storage Oyster-Feast should be refrigerated (33-42°F / 1-5°C) before and after opening.
