Interesting read.
As far as the technical/chemistry side of things, I have no idea. However I do look for legitimacy in articles like these, of which I couldn’t see any. They say they are scientists and given the technical knowledge, probably are but there seems to be nothing to verify this.
I have no doubt there are marketing hype with a lot of products, they are a company after all. But until I saw some validation of reports such as these, I would be inclined to take it with a grain of salt.
It will be interesting to see what the other experienced keepers have to say.
Thanks for sharing.
