Ponds & Aquatic Plants

Used Activated Carbon

19 years ago

Maybe a silly question but, I'll ask it anyway. After you use activated carbon and it presumably reaches it's absorption threshold, is there any use for the used activated carbon? From what I read, it has a tremendous amount of surface area. Can it be used to breed bacteria in your filtration or should it just be tossed in the trash?

I think that I read in another forum that it could be boiled and reactivated.

Happy ponding,

Hi
If it is the superfine type of AC it requires very high temps to reactivate but it certainly is a great bed for a bio filter even after it's stopped absorbing. Another great use for it is a soil additive for potted plants.
I've never used it very consistantly because of the expense except in marine aquaria.
