Easy question:  Can you reuse granulated carbon?  Of course, it has a limited life, but I am talking about putting it in the sump for a few days, removing it for a week or so, then dropping it back in.  Does it need to be kept wet, or should it be rinsed out with RO water between uses?

I think the reason is due to how carbon functions as a filter.  As I understand it, carbon has lots of porous surface that traps gunk in it.  Without a way to then remove said gunk from the carbon I'm not sure it can be reused.   

If there is a way to clean the carbon after use I'd sure like to know though!

Of course it cannot be reused after it is exhausted.  If the carbon has a usable life of two weeks and I just use it for three days, can it be stored and used again?

Still wondering if the carbon can be reused several times before it is depleted.  Am I the only one so cheap that he does not want to throw away potentially useful media?

I am also very cheap and have developed a way to reuse toilet paper.  Just trim off the clean parts and stick it back on the roll!

I feel it is possible to clean activated carbon with Hydrochloric acid, as the acid will dissolve the organic compounds. Resulting in clean carbon media, I would be curious to see if this works as it is how carbon is cleaned in factories. Not sure if this is something worth looking at as it would be harmful if not done correctly.
Probably just cheaper to buy new.

Just like re-using aluminum or iron phosphate, it will lose its efficacy.

Although, totally worth a shot. :)
