Snake oil or no?

Has or does anyone use Reef Biofuel from Brightwell Aquatics as a means of nitrate and phosphate reduction? Is it any good?

Most likely just bacteria

Even more likely sugar and/or vinegar and/or just maybe alcohol.

Assuming it is a carbon source like it claims (e.g., vinegar or other organic), it will work. Whether you want to use that brand without knowing exactly what it is, is another question.
