I'm sure their basic nutrient products are fine. For example, their iron supplement will contain iron, and will work indistiguishably from any other iron supplement.
However, they also have some "magic" products. Like FlorixAxis, claimed to supplement carbon, but containing no glutaraldehyde. I had the opportunity to get a bottle on clearance for $2, so I did just out of curiosity; though I expected nothing. And that's exactly what I got. No effect whatsoever even at triple dose, in a variety of low and high tech tanks.
Yet a very small number of people swear by it. Rather than doubt their results, I think perhaps they had a micronutrient deficiency that was addressed by the humic acid component, rather than it being an effective carbon supplement.
