I've considered this. All carbon really is, is a super-high CEC (Cation Exchange Capacity) substrate. The problem is that the CEC is so high, that it would strip the nutrients from your water column pretty quickly and form bonds strong enough not to give any of it back. Most modern carbon sources do not leach nutrients back into the water once they are removed.

haha ok Sam, thanks for the info....see, i knew that it had high CEC, so i thought...hey it would suck up all these nutrients...and perhaps hold it in the substrate for the plant roots to take up.....but i guess i'm wrong then??

another thing...doesn't carbon lose its effectiveness over time??? i 'm not sure where i'm going with this...just trying to learn more about carbon.

I was contemplating useing "spent" carbon in the substrate. Not really sure what the overall effect would be. It seems that once it has done it's job absorging organic compounds in a filter it could be used in a deep layer below the substrate and release those organics slowly to root feeders. Bio-degradation might play some role in this release. This, of course, is all speculation> I'm not sure if it would actually work.

does anyone foresee any problems that might occur??
