I think they mean that the bags are not only able to allow O2 in, but
CO2 out. It wouldn't help much to have a bag with a CO2 build-up and 20%
O2, the fish would still be dead. Kordon is a company on the up and up
in my experience. If you contact them asking for technical details on
any of their products they are happy to answer. One time I made the
mistake of asking them how Amquel works and I got a packet in the mail
that read like an article submission to a chemistry journal. It was all
documented in meticulous detail.
