Anyone heard of this stuff?

I was on monsterfishkeepers and stumbled upon this?

Aquachar.com

I think I’m going to purchase some and try in on the clownfish system.

Seems to me it would be good if you have mangroves or other plants.
But does not seem so great if it is really just for filtration.

THey kept messaging me and saying they had support for their claims, but they kept sending me claims instead of support.

Interesting
This is why I posed the question
Thanks to all y’all

It's been a "thing" in aquaponic circles.... but anyone doing it commercially doesn't use that, its a hobbyist product mainly. I never gave it even a glance, too loaded (people fighting, no proof, etc)
