As an avid gardener and aquarist I felt like a colossal fool after reading on the subject of a near permanent fertilizer, biochar. Used by South Americans for millennia. A lot of people balk at using it because soaking charcoal in urine for a month seems a bit outre to them.
And while reading this I began to kick myself hard for all of the used activated carbon I threw away during the course of my three decades of fish keeping. Used aquarium activated carbon is *perfect* biochar material!
So here is my attempt to leave the world a better place than when I found it. By connecting a former waste stream to something incredibly useful.
Thank you, that is all. https://en.wikipedia.org/wiki/Biochar
