I've been using a pre-made media from one of the sponsors here (not going to give the name so I don't hurt their rep) and I've had horrible luck with it. I tested it side by side with another sponsor's media and the latter out-produced the other culture (with the crappy media) basically by 100%. I'm looking for another media to purchase, and I was wondering what you guys are using. I'd like a just-add-water media. Please tell me the sponsor who sells it. Thanks!
