It's a waste IMO. I'd use beta glucan but that's about all.
With vibrance you soak the mysis in the vibrance and then put the mysis in the tank, when pouring the mysis in the system it does this strange thing, it gets wet. The vibrance starts coming off and going loose in the system. The best way to enich is to gut load, otherwise I say forget it. I haven't enriched, ever. My WC is somewhere over 6-7 years old, never a disease.
