Stanlalee - Frozen rotifers come from China and are freshwater rotifers so they don't naturally have the essential Omega-3 fatty acids that marine organisms need. The preservatives in all the Reef Nutrition products are nothing but vitamins such as ascorbic acid (vitamin C). You can verify this by looking on the side of the bottle - they are all listed there. Our 'preservatives' are actually good for your animals
Samstersam - I know there was a picture of something posted a while back. It didn't come from our company so I can't verify quite what it was. Have you even eaten an oyster in the summer? You've probably noticed that they go from being firm and sweet in the winter to flacid and creamy in the summer. That's because they are getting ready to spawn so they convert much of their muscle tissue into reproductive tissue.
To produce Oyster Feast we use "spawny" oysters that are harvested at the end of summer and have ripe gonadal tissue and ovarian tissue - fully of eggs. The only way there could be no eggs in Oyster Feast would be if we filtered them out. And since we don't have any other products that use oyster eggs, that would be just plain silly
The only way to really know which of the various oyster egg products are going to work best in your system is to try them all, and stick with the product that works the best!
Putting an oyster in the blender and grinding it up will produce food for many of the larger mouth animals in your system, but it won't produce particles in the 1-100 micron range that many corals need. Oyster muscle tissue is long and stringy, even ground up. If you can purchase "spawny" oysters it should work, but stores typically don't sell those because nobody wants to eat them.
