Does any type of charcoal work? I have seen fish charcoal and didn't know if there were any chemicals in it that would hurt me if I made a filter using this method. Also, how about burnt wood charcoal?
The main problem with run off water from your roof is the stuff that runs off with the rain water...such as bird poop, shingle granules, etc. Also many times the rain itself is not the purest of water but when it is all we have we will have to find a way to make it work.

On another post someone had mentioned that you could possibly get toxins in you rain barrels from you shingles. Is that true? Another question will a charcoal filter that kind of stuff?
