Oyster eggs are approximately 40-50 microns in size; they are soft and very nutritious being high in protein and omega 3 fatty acids.Size is a very important consideration when feeding corals. Oyster Eggs are from ½ to 1/3rd the size of a rotifer and approximately 1/8th the size of an Artemia nauplii. Oyster Munch is a mix of both oyster eggs and ovarian tissue (1-200 microns). Oyster Munch is suitable for SPS corals, LPS corals, sea fans, filter feeders and inverts. Shake well before use. Add 1 – 2.5ml per 100L to a high flow area of the tank daily. For target feeding, premix 1 part Oyster Munch with 4 parts aquarium water. For new tanks we recommend you start with half dose then slowly increase to full daily dosage over a month. Oyster Munch will give a strong feeding response from your corals and other tank inhabitants so if feeding other coral foods, a good tip is to use Oyster Munch first then once you see a feeding response in the aquarium add other feeds for maximum uptake. Note that colour variations in this product are normal as it is wild harvest. Ingredients: Oyster Eggs and Ovarian Tissue, Saltwater, EU permitted antioxidants.
