Pete, sorry, I mis-typed. I am working on trying to breed some clownfish and was in the process of starting a new culture of brine shrimp eggs. I do feed my horses frozen Mysis with a dusting of Vibrance 1.
The only variable I can think of that has changed since December, is that the last time (10 days ago or so), they were out of the San Franciso brand and I bought Mysis from a different company. The shrimp in these cubes seem to be very small and there is alot of "juice". I have a feeling that may be the contributing factor.
Also, not to be negative, but I’m a Veteran. Is there any company in the USA that makes this product? Every one I see is made in China. If not, let me know and I will grow and enrich them myself if possible:)
