[APD] Re: Refreshing old substrate (repost)

["Steven Pituch" <spituch at ev1_net>]

You could do a  "roll your own cigarettes ala Walstad".

Get some garden soil, and wax paper.  Put some of the soil on a piece of wax
paper.  Roll up the waxpaper into a tube and scotch tape it closed.  Insert
the soil cigarette deep into the substrate.  Do this all over the tank.
Gradually, the paper will disolve.  If you want to speed up the process take
a knife and stab the substrate where you pushed in the cigarettes.  This
will break open the wax paper tubes.
This is all detailed in her book "Ecology of the Planted Aquarium".
