Charcoal as a substrate?

I have been wondering if plants would benefit from used activated carbon. I understand that clay is used because it holds in nutrients but could carbon work in a similar way?

I assume you would need to soak it in ferts for a bout a month to get them to hold nutrients needed but then has no way of controlling how fast they disperse. Would not recommend.

I have heard of people growing cryptocoryne in coal slag.
I would do some investigating regarding different substrates and additives.
Charcoal can do many good things for plants and increase growth depending on species.

Charcoal is not ideal because it's super light (not heavy). It'll swirl around your tank and will be a mess.

Coal slag is another story. It should be heavy enough but it might have traces of petroleum in it.

black diamond blasting media = coal slag
i don't know if charcoal would really be a good thing, but i don't know what harm it could do unless it were treated in a way that would be harmful to an aquarium :P

charcoal breaks into fine dust particles which will swirl in water as already mentioned. Its also more expensive than normal aquarium gravel.

I was just curious since I accidentally spilled some when I was seeding a new tank with a filter bag. Thanks for the input.

I've never researched to understand the basis of the claim, but I've read many places that charcoal has been linked to head and lateral line erosion in fish??
