Re: [Killietalk] Poly Filter

["M. Frauley and G. Elson" <fraulels at videotron_ca>]

I know the cichlid crowd often swear by poly-filter for shipping, but
one thing that strikes me is that whenever I have received cichlids with
it in the bag, they've been on the road less than 24 hours. We tend to
trust killies to survive much longer periods in very small amounts of
water, especially when they go to shows or auctions.

My question is one posed by an English teacher on a list full of
chemists... do the types of absorbent materials and resins sold in the
hobby ever leach back the chemicals they have picked up, or do they
simply reach their 'capacity' and cease to function?
