Hi,
We have seen many alternatives on filter media - ( plastics, rock,
shredder,..), but does anybody has experience with using magnetic tape
( video, audio) as filter media?
Since it is all about creating a huge amount of surface this substance
could fulfill our needs.
One reel of a video-tape delivers an enormous amount of surface. The
question I have is about the chemical reaction in water of the tape: is
this chemically inert?
Is there any chemical expert in the group who has an opinion on this
question? The test I did was putting the tape in water for 3 months -
the water is still cristal clear; I observe no visible contamination of
the water sofar. Or has somebody a suggestion on how to test eventual
contamination?
