 in there, but the formula is always on my website and in my books and available. You can buy the commercial products too if you don't want to make your home brews, but it's available either way. Where do you find it if I do want to buy it? You can buy it online. The Medina company sells Medina Plus, which is the commercial version that I recommend the most because it's got fish in it and it's got a little bit more horsepower.
